Steve, 69's are my fav Mustang too.

Hey Linda, Thanks for watching and checking it out, he is one proud owner!

My very fist car and my daily in HS was a 69 Mach 1 loved that car too!

Late to the party, mine was a 70 Mach 1. Found with huge hole in Cleveland but found a 2 bbl Windsor that I put ported 69 heads with screw in studs, port matched Ford alum intake Boss 302 solid lifter cam. Just my Woodward screamer in the early 80's.

Yes he did a great job on the build, thanks for watching and commenting!

Steve, The Cleveland motors are great to build and do well with high rpms. I have owned a 71 Boss 351 and currently have a 351 4V, 4 speed in a 70 car and they are great street cars with plenty of power and torque stock. It sounds like you built a killer motor and what a score getting a 4 bolt main bottom end in your Mach.

@MC1...Thanks for the reply and nice chattin with an old Ford guy...yes it was amazing when we tore the motor down...back in '74 I wasn't the Ford "expert" I am today so when I saw the 4 bolt mains I didn't exactly know if the Cleveland's came that way or not, and neither did my Dad...and of course with no internet we ended up at our Ford dealer's service/parts dept asking about the block...they didn't know anything but when we gave them the casting number of D2AE it showed under the '71 Boss...but oddly also showed under '71 non Boss engines...anyway we had one. All these years later I realize the blocks are the same except the the 4 bolts have 4 bolts on all mains, which can be installed by any machine shop...of course my engine in '74, it was obvious the engine had never been out of the car before so it came from the factor like that...she was a running car and as Sr.in H.S. it was fun having the fastest car in Cocoa Beach...one funny thing about the car was (which much to my chagrin I learned twice before I actually believed it), was the exact moment the gas gauge needle touched the empty line, the engine died...lol...just one cough, one spit and she died....the 1st time it happened me and a buddy were incredulous, we thought we had an electrical problem or possibly a clogged fuel filter as we were used to fuel gauges going well past empty...we finally put some fuel in her and she fired right up...I thought I must have misread the fuel gauge and sure enough next time I ran her down to empty I watched it closely and wham the moment it touched, she died again...even back then I got a huge kick out of it and today it still makes me smile.

You probably had a 1972 R Code 4 bolt main, in 72 Ford dropped the Boss 351 but offered a slightly de-tuned Boss 351 motor. Difference was you could get it in any Mustang , Coupe, Sportsroof and covert. That motor became the service block for the 71 Boss as any 71 boss would have had a D1 casting in the prefix. Same bottom end though with 4 bolt mains.

MC1...One last comment...I have had a few high end Hipo mustangs over the years, including a real '65 fastback K code, a '69 and '70 Boss 302, the aforementioned '70 Mach I, the first fuelie in '86 and the coupe de grace a 2000 Cobra R model and have always wanted a Boss 351, but I just can't get past the '71's styling...I hated the car when it came out as a kid and it is still one of my least favorite pony car designs...I'd rather have a '71 Torino 429 SC...anyway I could never bring myself to buy a Boss 351 even though I absolutely think the engine is at the very pinnacle of Ford performance back in the muscle care era....okay later...hey speaking of 429 SCJ Torino's...do you know of any for sale? Obviously I can check the internet but thought I'd ask.

Yes the 71's Mustangs are a love it or hate it but those big bodies make for a great ride. No but I did have a 70 Cobra 429 SCJ Drag pack project , 4 speed car too that was in restoration. Someone saw it on the channel and the offer was too good to pass up. Kinda wish we still had it, killer car and it really hauled ass. kzfaq.info/get/bejne/sLV3nMqBuc7doqM.html I am not aware of any 70-71's for sale at this point.

Nice meeting up with you Robert, great car and hope to see you at another event in the future.

ever run it in the 1/4?

Very beautiful Mustang always enjoy seeing it at the shows! Pacific paint and body also painted my Chevelle about 18 years ago and the car absolutely still looks amazing as a day they painted it .Dennis is a true treasure to the car restoration business!

Robert, would you please share the special cam grind? Thank you!

I've never taken this one down the 1320...This car could use a MUCH stickier set of back tires to gat a decent 60 ft time..Pretty sure it's capable of high 12's the way it sits...The Car mainly see's a lot of car shows..Just scored my 60th trophy yesterday...

Yes still hard to beat a good Mach 1

The Mach 1 or the Boss 351 ?

Thanks Lloyd, he sure did a nice job on the build.

MrADVANCEDTEK so is that a hopped up 351 Windsor?

No it's a different engine family from the Windsor. It's a 335 series which is a later engine family that came out in 1970. Kinda confusing cause the same displacement and power rating for the 70 model year but it's a very different engine. The Boss 302 and 351 had very similar heads that had a canted valve design. I think that engine looks good to. Rare engine.

MrADVANCEDTEK thanks for the information. that is a really nice engine, i like the small block. What is the hp?

Rob Wright They had different rating for the 2v and 4v carbs can't remember the exact hp but the Boss 351 was rated at 330hp I believe. It was underated though. His Boss was modified if I understood him correctly. It does have solid lifters and a decent lope at idle so it's not stock. If your not into rare stuff and have money you could find a decent Cleveland block and get a set Jon Kaase P38 heads. They're a nice alternative and available. Finding a Boss 351 is not easy at all. I've only seen maybe 15-20 in my life.

I apologize. I believe I was incorrect about the Kaase heads working on a Cleveland block. I do not think they will. They are stated to work on Windsor blocks which have a different cooling flow within the block.

They do look great tucked under there and no rubbing either, special offset on that Crager

'69's are hard to beat, you should get another one!

It ain't a Muscle Car

My favs too, happy Easter George.

Yes this should be a 12 second car all day long.

Indeed it is!

Indeed, thanks for watching, always appreciated, have a great Easter weekend.

Thanks for checking it out! Pete, do you want a Mustang Connection channel sticker? Send me your address.

You'll have to send it all the way to India!!! It's okay if you don't. I'll be a constant follower for Mustang content anyways. Pete :")

Not a problem, I have sent them all over the world, no idea how good the postal service is in India from here but let's try it!

Is there a way I can PM you my address? Thanks! Pete :")

Yes it was 1 year only 1971. This car is a 69 Mach 1 with a '71 Boss 351 engine .

Cool, a real car guy, he did a great job on this one.

Correct as the title says it's Boss 351 powered and we discuss how that motor was put in the 69

I had a 69 with the 4bbl Windsor motor and a that I rebuilt with all the goodies. 4 speed car That thing was a beast.

Well yes this one is far from factory correct.

right on..
