I bought my first Boss 429 in April 1070, four months after I got home from Vietnam. I had seen a picture of one in one of the magazines and really liked the looks of that car. My first car was a 1964 Plymouth Savoy with a 426 wedge and a four speed. I was a Mopar guy unitl that Boss came out. I, like several other people, had problems with my engine thanks to a Ford dealer installing the 1970 solid lifter cam. There are four oil control plugs in the block that need to be changed when going from hydraulic to solid lifters and that wasn't done with my engine. After two years of getting jerked around on getting the engine fixed right, I took it out to Jack Roush in Livonia, Michigan in 1972. That car was no slouch when I first got it but boy did he wake it up. He turned my engine into a 460 using my rods and the pistons from a T series engine plus a 460 crank. I brought a Crane .600 lift 318 degree duration cam and lifters plus an Accel distributor. He supplied a dual quad intake with two 600 Holleys and titanium intake valves. He estimated the horsepower at between 525 and 575 and there was no doubt in my mind when I stuck a leg in both carburetors the first time. It got up to 7500 rpm's in a heartbeat and it had more to go but I didn't. I still have that car. I bought two others in the meantime which I ended up selling because I couldn't afford to get them restored properly. One of them owns the record for the highest price ever paid for a Boss 429 Mustang when it sold for $605,000 in January 2007 ($550,00 plus 10% to Barrett-Jackson). It was lot #1325 if you want to look it up. It's also listed under the 10 highest prices ever paid for a Mustang at auction. Wish I still had that car. Ed Meyer of Indiana had that car looking like brand new. All three of my Bosses were Candy Apple red and they were all 1969's. That dual quad intake that Jack Roush sold me is reportedly one of only 25 made by Ford. Maybe having the engine built lessened the value of the car but I would never put it back to stock. That car is my pride and joy.

When NASCAR stock cars really were "stock" cars. A golden era. NASCAR today is but a mere shadow of these great days.

I am a die-hard Mopar guy , and this is an interesting video. I like reading through the comments sections. Best thing to do is not be biased too much. Any intelligent person knows, that a handful of money and knowledge can put most engines at serious competition with each other. Back in the 70s we didn't have a lot of money, so we stuck to the simple go fast changes. Camshaft, lifters, better valve springs and retainers, rear end gears, shift kits in the transmission, stall speed converters, and headers. For us Mopar 6-pack guys, the Performance Kit to change the springs in the vacuum end carburetors was also a must. Other guys might opt for Progressive linkage. Ford guys had plenty of opportunity, and any Mopar guy that had a first look at some of the performance heads that Ford produced got their eyes opened. Ford was no slouch. The street engine Ford Boss 429 had to be mild enough to drive. And that was it's choking point. Make no mistake about it though, this is a great platform that just needed some performance goodies like most any other car manufacturer regular production engines. It's really at all about what you personally like oh, but at the end of the day they are hunks of Steel, Cast iron, and various other metals that make up an engine with a different manufacturers badge on it. hail to all of my Gearhead Brothers out there. I sure miss the 70s, when things were more laid back, cool music, and our world wasn't wound so damn tight

Watching the manufacturers chase each other in those days was something we’ll never see again.

I love every engine, no matter the manufacturer, that started with a 42... but that Boss 429 Mustang, especially the 1969 model with the four headlights, is my absolute favorite

Bob Glidden was great. Rest in peace

Many years ago I would see a red Boss 429 Mustang with the vanity plate SEMIHEMI just driving around the streets in NY. What a sound that car made :)

I was only able to attend one NASCAR race in person. It was at the Michigan International Speedway, in 1976. The late great David Pearson won it driving the famous #21 Mercury with the Boss 429, for the legendary Wood brothers team! Watching him coming down the front stretch while leading the race,the sound of that Boss 429 had a distinctive sound all it's own! He dominated & won the race. I'm 68 now & I still watch the races on TV, but it's nothing like being there in person, but a helluva lot cheaper! ❤🏁🏆

fastest car i ever rode in was a 70 mercury cyclone spoliler 428 scj, yes no typo a 428.....

Thanks for using the Schartman Boss Cougar picture. We have had that car since spring of 1974. Today totally restored and raceable. Have played with a few Boss cars. Doug Herzog

In the Mustang, the Boss 429 was choked by restrictive intake & massively choked exhaust.I do love you mentioned the 427 sohc(cammer) The cammer was never approved because Chevy found out about it & fought it's approval with all sanctioning bodies...this also is what got The Hemi banned.

I had a 1969 Boss 429 in stock form, my 440+6 cuda would blow it off the road easily! then i bought a 1970 Boss 429 that had been worked a little......Holman and Moddy solid lifter cam, dual blueprinted holleys on a medium riser intake, headman 180 degree headers,, scatter shield and McLeod clutch.........OMG that was a tire boiling bad ass! the power from 3000 rpm and up was unreal that car would "relight" the rear tires at 45-50 mph going into 3rd gear!

Long live the internal combustion engine and the boss 429 what a beast. I had the pleasure of riding in a mustang boss 429 when I was a kid and what a beast it was. 💪🏻💪🏻💪🏻

Not a Ford guy. But engines that perform demand respect. That is an engine that has earned it.

Nobody was better than Bob and Etta. Bob made magic with his intakes. Remember the guardrail wreck at Atlanta when he took off his firesuit jacket to cover the intake before the camera crew got there?

The 351C was called a "Baby Boss" so I understand the 429. They both had canted valves, huge ports and used the same spark plugs. The 351C even had a bigger (780cfm) carb! Great video!

This was the biggest engine I've ever seen in a 2+2. The whole bay of a 69 mustang was this engine. Glorious!!!

The Boss '29 and the Cammer are fantastic looking and legendary. (426 Hemi looks great too...)

I'm a Chevy guy but always thought that the SOHC and Boss 429 were the baddest of the bad.

Good job, Andy. The real savior of the Boss 429 in drag racing was Alan Root, who's design update ( given a Ford P/N) addressed some of the original Boss head shortcomings. This basic redesign, tweaked by Kaase, Roush, Glidden, Leonard and others, powered those 1980's IHRA and NHRA Pro Stock cars to such dominance.

And now, we have men like John Kaase out there making the Big Boss not only reach, but exceed its full potential.

Back in 1969 of all magazines that actually tested bone stock cars the 1969 Boss 429 T was number 2 of fastest cars. Getting beat by only the ‘69 GTX 426 Hemi Auto with a 4.10 gear. Very close the 426 went 13.32 @ 107 vs Boss 9 at 13.34 @ 107. Bigger carb on boss with better exhaust and they ran very well. I owned a 1 of 6 1967 Mercury Capri R code (427 8v) 4 spd and it was no doubt quicker than my friends 1967 Hemi GTX. I did add a limited slip diff to the 3.89 gear. Ford refused to put locking or limited slip rears in the 427 comets or Fairlane’s for “safety” so any magazine article from back then was with a open diff. Crazy really but one still ran a 13.51 @ 108 with open diff.

As a “Ford guy” I never knew the entire story of that engine! Thanks for a great vid

Bob Glidden and Jack Roush were my inspirations in the day. The final picture reminded me of my car when it had the tunnel ram sticking through the hood with the holleys topped with velocity stacks. My engine was a 302 tho. The Boss 429 was only a dream. The Mustang with any of the Boss engines would be tops.

Back in the 70s, a friend of mine, who was a racer, had a few of these engines in his garage, brand new and still in the factory crates. If only I would have known what they would be worth today. Thanks for the history.

Thanks for the information about the Boss 429. John Kasse and Jack Roush are also two of the best Boss 429 engine builders.

growing up I knew the greatest car geek ever, he was a school teacher in metal trades, and always at auto shop across hall, he helped kids stay out of trouble & helped them focus toward cars, trucks, metal work, yes helped me from being a dropout & who knows what. he gave his life toward helping kids, and never had wife or family, died alone in nursing home a few years ago. no idea what happened to his cars. he lived in rural VA. anyway he owned a 1969 & 1970 Boss 429 Mustangs, I know he had a few 427 SOHC powered vehicles, 1 was a drag race only mustang, and a few spare engines, a couple Torino super cobrajet drag packs, 69& 70? or 68 & 69? 1 was automatic, which I helped build in classes, 1 was 4 speed. a radical 78 king cobra Mustang II, yeah I know, but for a daily driver with .700 lift cam in a small block, it was radical, he had a totally bad ass pickup for a more fun daily driver with a tunnel rammed dual carb 429, all those in the mid to late 1980's

My Brother had a 1970 Mercury Cyclone,it carried a 428 SCJ under the hood.This car was a ferocious beast.

I was fortunate enough to attend the U S NATIONALS,many years in a row. Watching all those different Ford racers, from Stock to Pro Stock & all the other different classes in between! There was one man that raced in an Stock class with a 352! I didn't remember the NHRA banning "Ohio George" mustangs, powered by his revolutionary, turbocharged Boss 429's. I do remember watching him race in them! Great memories I'll remember for the rest of my life!

The France Family, ruining innovation since they created NASCAR

Definitely a work of art, a beautiful engine for sure. One wonders if the DOHC Coyote motors may one day be looked back on as fondly.

The biggest misunderstanding about the Boss 429, is that the street versions were detuned drastically. Mopar did a better street tune to their Hemi than Ford did. The Ford was built to go after the Mopar, and the race version did a lot better. Between those two engines and what they could have done to produce even better versions, was the number one reason NASCAR put the halt to them. They were just getting started good.

They all good excellent fire breathers, but the "Blue Oval" produced the GT and rewrote the book of land speed

I cleared some land for a man back in 2008 he gave me a 1969 Ford short bed pickup truck,has a T code boss 429 in it,but he had it rebuilt with modern part's, And it pushes this old truck pretty darn good, especially at higher RPM I can see why it wasn't good for dragging but all in all for a solid street legal hot rod it's a beast

My Uncle had a boss 429 he ran at Atlanta motor speedway in the road racing track. He dominated with it. It might not have been a good drag racer but it was a great engine for the nasser and road racing tracks.

When I was a kid and just learning about cars my uncle helped a friend of his swap the intake on his Boss9 he tracked on the weekends. To this day I swear my uncle was able to stick a beer can in the intake ports and not hit the sides, I'm probably mixing up my memories but I remember they were huge. It took a few years to really appreciate that I got to work on such an engine. Great video!

FORD's two greatest big block engines are the FE-427 and the 427 SOHC. The 460 was also pretty good, along with the 428 Cobra Jet engine. And the 351 Cleveland is the baddest small block to ever be produced by anyone. In the original movie, "Gone in 60 Seconds, a 1973 351 Boss Ram Air Mustang was the star of this show. That car got put through its paces and then some. Great Chase scenes.

I'm 51...my dad owned a performance shop in Canada...I had all these guys on my wall when I was a kid....great video ....thx Andy

My dad was a hemi guy. He had the 426 in his Plymouth satellite and his opinion of this motor was it was a dog. He said he wasn’t impressed with this motor and being that he kept his car pretty much on the stock side, he said the only car he lost too in the 1/4 mile was a new corvette with a 427 big block. He said the vette was 1000 lbs lighter then his car

In my Car Show years.. production assistant.. I went to many a Show.. Only Once Good Guys Show in the San Francisco area.. Seen Boss Stang on the road to the show Highway driving.. then found him.. Man oh Man.. up close it's Crazy looking.. this was about 12 years ago now.. hope he's still driving it.. but you know the price on these has Gone up.. to say the least.. Great Post UNITY..

He’s right the Boss 429 was a crazy good looking engine, and the boys in Georgia have learned how to make it crank big HP out of it. The Boss429 Mustang was every muscle car admirers dream

8:59 Amazing to see a twin turbo setup like that on a car from nearly 50 years ago! Talk about being ahead of your time.

When I was a teen I had a Ford Motorsport catalogue from the 80s (I was fixing up a Mustang at the time, and was working on the engine). And all the motors and parts were Boss 429. There was a large selection of heads. I was just building a daily driver small block. But it was interesting what you could order straight from Ford, in an era when factor V8s didn't even have 200 hp.

Thanks for the video! Back in the early- mid 70’s I drove a warmed over 1970 Mach 1 with the 351 Windsor. Of course as a young blue oval gear head I lusted after the Boss 9. It was the holy grail car for Ford guys (the SOHC was so rare it wasn’t really thought about). I saw one at the drag strip around 1974 and it actually ran pretty strong. As I recall it ran about a 12.1 with headers, cam, better carb (Holley 3bbl) and slicks. That was actually really impressive back then for a street car. You are totally on point about the engines issues. With the humongous intake ports it was designed to make tons of power way up high in the RPM range when coupled with the right cam and carb. The problem was (per Jon Kaase) that the 429 ci was just too small to create enough pull through those massive ports. As you pointed out a better cam and carb helped up top, but only so much. They still were really sluggish in the low to mid RPM range. Reducing the intake ports via epoxy actually makes the engine run way better all around. The only way to make the as cast heads really work is to add ci. A LOT of ci, like way over 500. Regardless when a blue oval gear head like me sees those Boss 9 valve covers under the hood I hear the angels singing. I guess it’s similar to how MOPAR lovers feel about the Hemi!

Emission laws were the Achilles Heel of the Boss 429. A 735cfm Holley? See the smog pump? Just go to Muscle Car of the Week, Top 10 quickest Muscle Cars of 1969. Hosted by Kevin Oeste. Posted a couple of days ago. #1quickest? drum roll.. 1969 Roadrunner HEMI auto. 13.32 @ 107.65mph. #2 quickest? gazoo.. 1969 BOSS 429. 13.34 @ 107mph.

I did race the Boss 429 Mustang for a short period while driving for Kar Kraft. The best time I had was a 11.99 in a 1/4 mile. That was in 1969. We had a experimental engine 427 car that could beat it by 1/2 a second, any day of the week.

The Boss 429 had intake ports you could just about roll tennis balls down. We used to fill the floors of the intakes with Devcon and raise the ports into the rocker area resulting in about a golf ball sized intake port giving the enging great low and mid range power for street/strip and truck pull motors. Even bored and stroked them to 618 CI

A very well laid out description of the boss, seen a 500ci prototype NASCAR Torino at a car show,,, hearing it start was historic!

We built those engines at the Lima Engine Plant. I drove many pistons in the Blue Crescent engine (our code name) for the 429 boss. We were also making the 429/460 regular engines with wedge heads. Some of those went into the Super Cobras. We made some 460's for the presidential motorcade. The 429 boss didn't have a head gasket, O rings around the cylinders and neoprene rings around water ports, etc. Valves were ,010 bigger that the Chrysler Hemi and the intake/exhaust ports were huge, heads were aluminum. Each rocker arm had it's own pedestal and run on needle bearings. I saw several running on the dynos at the plant......one at 5000 rpm for many ? hours just to see what would give up. I believe some went almost 24 hours. Exhausts would be glowing............!

That there BOSS 429 motor is a good looker that's fer sure!

Absolutely a great engine, ironically NHRA never tore down or investigated Don Garlits who had almost unbelievable success with Chrysler.

6:00 mark - The factory ram air was very restrictive, but was required in certain classes. It was competing in a class of Hemi's that came factory equipped with dual quads. In Stock type racing it was a 11- second car. I recently posted a story on this. In 1970 Kar Kraft offered a kit that included jets and other stuff to make it 0.20 faster then a 1970 SCJ. Great Video!

I am not a Ford guy but I just love the 429 boss Mustang. I saw it in a magazine round 1970 as a kid. When I get rich I going to buy a matching nummer car.

Actually the Chrysler 426 Hemi suffered from the same problems on the street the 440 usually would beat it unless the hemi was in perfect tune simply because the port velocity was low and even then in street racing the 440 and the 454 Chevy and others still could beat it a lot of the time. These engine did not come alive until you hit about 4800 rpm or so and even then because of the compression and the cam lift and duration they still could not take advantage of the heads. That being said put in 11:50 compression or more and a lets say .650 lift solid cam then the hemi would run away from almost everything I know I owned two of them. The Boss 429 had the same problems but once built right to take advantage of those great heads the only thing that could run with it was the 426 hemi built the same way. The truth is the Boss 429 and the Chrysler 426 Hemi ruled it all only when built to take advantage of the heads those of us who lived racing in those days knew this to be true.

-When I was 12 in 1978 my parents took our Argosy trailer to a KOA campground in the Irish Hills region of Michigan, about 60 miles from our home. Michigan International Speedway was nearby, and we went there. There were stock cars doing testing that day, and one of them was a white GM car . It went past us fast, and later I found out it was Cale Yarborough, who is in this video and just passed away at 84 years of age. I think that Carle Yarborough got a nice long life and he LIVED it, racing cars!

My father worked for Ford in the 50's and 60's as VP of the Truck Div., then left and bought up several Ford, Mercury, Lincoln dealerships throughout the mid-west to revive, we also got the exclusive Shelby Cobra and de Tomasso Pantera franchises for all of the midwest (his factory connections paid off) because he sponsored Cobra Racing. He ordered me a custom 1970 Mustang "Boss", but instead of a 302 ci V8, mine came with a 351ci "Cleveland" "Semi-Hemi Head" V8 and dual Quads, and factory pipe headers. Because it (with the 351 Cleveland, built on the Ford Small Block) was so light, it was FASTER than the 428 Boss, and I clobbered every Hemo Dodge and Chevy 427 a the drag strip. The 351ci Cleveland Semi-Hemi was a far better engine than the 429 Boss or the 427 "Cammer".

This is a brute of an engine. Tell you what, Sam is definitely the man to talk to concerning anything 429. Very interesting video, thanks

Way back as a teen I was a passenger in a boss 429 a church member and a 69 hemi road runner, my chevron boss son. I love Ford but was brutal in 4 shift, banging & lifting the stang. But didn't feel the speed. But the hemi. It's was a special edition was just one one long lift and we were 60-70'area. The close I felt that again was in a Yamaha GS 1,000 the first model 11 s bike. The second gear pull 20-70 was like 2-3 second. There is a difference from brute torque power. Than on the cam or live nitro power that can't be beat. Torque is fun & show & noise. LOL. His hemi was all black with back 50s on center lines beautiful car. It's has to be around. And the cam hooker sound was perfect.

I know a couple guys out of Yucaipa that had a machine shop...DODD & SPILLMAN...Well one of them had a 429 in his truck....008 clearances on pistons.. ha...he said it didn't run right until it got good and HOT...YOUR VIDEO MAKES FANTASTIC SENSE...BECAUSE ITS TRUE TO THE BONE...TY...And I would love to have one of those 427 SOHC ENGINES IN ANYTHING....DANG GOOD BRUDDAH!!!!!

I've heard with those ports and heavy internals running 9500rpm for hours was cake and what that motor loved most.

This is the parallel between the 426 Hemi and the 440. Everybody gets all orgasmic about the Hemi. As a real-world drive, I have seen Hemis whipped by 440s many, many times. So here's the mighty Shotgun motor. If you check the figures in the era, not only was it a lot more money then a Cobra Jet, it wasn't as fast in most cases. Looked great. Wasn't better.

I raced a 70 440-6 Cuda against a Boss 429 Mustang, 4 speed against 4 speed and embarrassed the 429. It was just Ford meeting the Homologation rules and not a great engineered street car. It is a beautiful and impressive car, but unless you were willing to change it from original, a 428CJ would blow it away. Stock vs. stock, the 426 Hemi was a better street engine. In NASCAR, the Boss had a 60 Hp advantage over the NASCAR 426, but the aerodynamics of the Daytona and Superbird winged cars made up for the power disadvantage, keeping Chrysler from having to re-tool another version of the Hemi. I miss being able to buy these cars for hundreds in the late 70s early 80s.

one million thank you's to the kind good folks who put this history lesson together and shared it with the rest of us. B R A V O...!

Absolutely great video sir, from the words to vintage clips to photographs, all add up to a Ford lovers dream. Thanks for putting it together, I will forward it to my dad!!!!

Thanks Andy, that was a great history lesson on the Boss 429. I had no Idea.

The Boss 429 was the Mona Lisa of engines she had the look & muscle.

In 1975 I saw a 1970 Boss 429 in London England. It was Ford Blue, an awesome.

So . . . too much cylinder head ? Where have I heard that before ? AH, YES, THE BOSS 302 ! 😁 Cool story, thanks ! 👍

A friend had a Boss 429 Mustang. Those motors had 'O' rings for head gaskets, always leaking!

Thank You for your service and the great fast fords story..

I was a weekender at Sunshine drag strip in Florida. I had my S code prepared by Speed Specialties of St. Petersberg. With cutouts under the doors, I ran "A" stock and did very well with the Bow Tie guys. It ran quicker than the stock SS 396's at that time in 1970.

this guy is completely right. the BOSS 429 was designed for the super speedway and didn't make great low end torque. get it up to speed and it was a monster. on the drag strip not so much. had two buddies, one had a BOSS 429 the other a 427 SOHC the 427 always beat the BOSS in a quarter mile drag.

What’s misunderstood? It was freaking awesome!

Now for eerie; the 2020+ Ford 7.5L Godzilla V8 reminds me a LOT of the Boss 429.

I am a true Mopar NUT, to the Core! but I can easily say that the Boss429 is one of the most Badass production engines built by Fomoco at the time. One of my neighbors had a grabber yellow 1971 429SCJ Ford Torino, and he Knew how to drive it HARD! I was very sad when he moved last year, he had a REAL DEAL piece of history with him that he took with when he moved out of the area, though Mopar's will always have my heart, but there is reason ford stands for, FIRST ON RACE DAY! Great video!

Great vid mate from down under 🇦🇺 Definitely one of the coolest engines 😎 🏁

Hey Andy thanks for history lesson,being in aus and no internet those days didnt know what went on,been watching some of Bob Glidden races,he sure knew how build a motor and race them

I in January of 69 ,. I was at North Western Ford, Milwaukee WI. I saw a 69 plan Jane while Sport Roof Mustang, It had the Boss 429 stuffed into it!!! WOW I was so impressed, I was home from Nam less than a month

Pretty much was Jon Kaase says about those heads. They need cubic inches or RPM although I wonder just how well some of the Mustangs were tuned. My Dad worked in garage back in the early 70's where the local sheriffs department would bring in their cars for maintenance and tuning. Can't remember the car but the engine was the 440. The sheriffs were complaining about the engine being a dog and so Dad started messing around with it and with the factory specified timing it was doggy but when he increased the timing around 10-12 degrees it turned into a beast. In fact he took one out on a Sunday and got it up to 140mph on the freeway that was near the garage where he worked. The next time he came into work all the sheriffs wanted him to tune there cars though he was told no more road tests.

I loved this video!! Anything that mentions Bob Glidden is tops in my opinion! 🇺🇸😎

I was pretty much raised at Gainesville Raceway and had the privilege of seeing Bob Glidden run numerous times. Even have a picture with him holding my freshly autographed Motorcraft Glidden Ford Thunderbird model. Those were the good old days.

Great presentation!

I knew a man who had a new 1969 Mustang Mach 1 with the Boss 429. Car shook

Ford made some great engines back in those days..

Cool video, Great job.

2:39 mark - Great Video. Since Fords production 427 High Riser (HR) engine was banned after 1964, Ford developed new heads and intake for the 427 called the Medium Riser (MR). They also changed the 427 block to a side-oiler vs the original top oiler

My dream car! Thanks for sharing!

The Boss 429 had a smaller carb than the Boss 302. Big ports hard to get air moving and once it would start the street engine would run out of carb. But they sold enough for the rules.

Double liked!! Love the Boss 429. Keep up the good work.

Liked the video. I'm mostly a GM guy, but not a "only like this brand and all others stink" guy. Agree with the part at the end that the Boss was one of the best-looking engines. It's bad-ass looking, for sure. And also agree about its checkered race history. It really just didn't do that well overall, until it was made with big cubes....and even then, it was spotty. Ford fans will point to Glidden....and that's true. But it was Glidden that made the Boss, not the other way around. No other Ford team was really even particularly competitive in the same time frame, that was all Bob Glidden then. He was ahead of the curve for a few years. With the aftermarket today, you can make anything run however you want it to. But I love hearing about back in the day, when racers had to run the best they could find from factory parts and they couldn't just order up a CNC set of whatever size heads they wanted to along with an unbreakable rotating assy. Well done!

In 1971, when I was a 24-year-old, looked at a used red 1970 Boss 429 sitting at a Ford dealership. It had 5,000 miles on the clock, and the asking price was $5,000. I was so impressed those 50+ years ago, and I'm still impressed today.

Excellent video,

The Boss 429 was also installed on TWO Mercury Cougars for drag racing.

I so enjoyed this video. Thanks for the great images from a better era!

Nice work. About the best story of the Boss 429 I've ever come across on KZfaq

Magic Andy. Sharing is Caring. Thanks for networking and talking with the Guru's.

It's unfortunate Ford didn't send Fairlane's to Kar Kraft to be modified. The 69 Cobra had 1 engine option. 428scj. It would've been cool if the B0SS 429 was a second option. Wait a tic! I'll save enough $$$$ and build my own BOSS Cobra! Thank you for showing this video. Love the history!

The SOHC would discharge a incredible amount of shrapnel when on Nitro and things went wrong. A few could pull the cams around and do better, but not for long. Short life on everything when on Nitro. It was successful, but very fleeting. One of the reasons for its rareity. They chewed them up quick. Thanks for the vid Unity. I miss Lou'ville. Kentucky is my Heart.

Thank you for your work

Growing up in nh. My neighbor had a blue boss 429 just sitting outside for years. I never knew how rare that 70 car was until I grew up
