Misleading title. This engine was never misunderstood. Period.

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

On the streets of 1970, the Boss 429 was beaten like a rug by Hemis and 440 Mopars, LS6 Chevelles and Buick Stage 1's. In stock form, it just wasn't a great musclecar engine. The CJ 428 was much better

Bill France being a fan of chevrolet had to give chevy a chance to win because they had no chance on their own merits. So he outlawed every thing the other manufactures made [ including other GM makes] to give chevy the advantage. This went on for more than two decades. To some degree still goes on today through Bill jr. This is why I have had no interest in nascar for decades.

the BOSS 9 ?

A good real article. Richard petty is no king. He....unlike most racers, had the total support of the cars manufacturer. They made the car, the custom engine and free parts. All other racers never stood a chance. And I think it was crooked that the racing governing body allowed it. Maybe some money changed hands. Any racers that beat the petty Corp. Conglomerate manufacturer cars...earned it. Enough of this kingdom bulls..t

I'm sorry ..... Yes this was great and a whole lot of useful information . I am60% deaf so the defect is on me not your video .

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

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".

A Ford dealer in my home town got a Boss 429 Mustang. I went to see it. It had a $5,000 MSRP. I didn’t believe anybody would ever pay $5,000 for a Mustang.

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.

When NASCAR stock cars really were "stock" cars.

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

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

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

Bob Glidden was great. Rest in peace

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! ❤🏁🏆

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 :)

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.

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