Ford produced far more SOHC and DOHC 427's than they ever used. They built so many that they ended up selling brand new motors still in the crate for pretty cheap prices in the late 60's. I know of 3 brand new never ran 427 OHC motors stil in their factory crates. There are actually quite a few of the motors still out there since they weren't actually used in that many cars.

The 427 OHC motrs could actually be considered a special production motor, at least more so than a 528 Hemi. The 427 OHC's were used in the factory built 65 Mustang AFX drag cars as campaigned by Gas Rhonda and such. They were built in very limited numbers, but the factory did install them.

NASCAR banned the Hemi for most of the 1965 season. Riachar Pety actually built a Hemi powered Barracuda and went drag racing to boycot the ban. The Hemi was reinstated late in the year, and Petty (and others) went back to NASCAR.

As stated above, that was only because of Ford's areodynamics. Richard Petty actually wanted to drive a Hemi powered Dodge Daytona (the Dodge version of the winged aero car) for the 69 season, but Plymouth wouldn't let him have a contract with their sister company. He went to Ford because their cars were far superior aerodynamically than the Plymouth Belvidere used in the 69 season. When Plymouth got their own winged warrior for the 1970 season, the Superbird, Petty gladly returned to Plymouth and the Hemi power, and went on to win the championship.

 

Hey Ev2Demon learned a lot in that last post. Thanks. You definitely know your NASCAR history. Where else but FTE.

 

Ford never made any 427 DOHC motors. They were in the works when NASCAR banned all OHC engines, so that project got killed. They did make several 427 SOHC's though and they can still be obtained. Last one I saw went for $25K.

Dodge guys can say it was aerodynamics all they want, and to some degree theymay be right. However, the 427 in it's various forms, especially the Tunnelport was right there with the Hemi in the power department and probably quite a bit better in the durability department. They were a force. That is in no way a knock on the Hemi, just a testament to the 427.

 

I've seen specs (HP & Torque) for the DOHC 427, so I assumed they built a couple anyway. I've never actually seen one, but like I said, it's probabaly safe to assume a couple were built.

Chrysler was developing a SOHC 426 Hemi for NASCAR as well. When NASCAR outlawed Fords SOHC and DOHC, as well as all other OHC motors, the program was scrapped.

 

Well, you may have seen specs for this supposed engine, but there has never been one piece of physical evidence that this engine ever made it off the drawing boards. Not a single 427 DOHC head has ever been discovered (rediscovered). There is some rare stuff out there that seems to turn up, but a DOHC never has. Couple that with several experts in Ford history who say it was never produced, and I have to doubt it's existence. That being said, 427 SOHC was, and probably still is the baddest factory engine produced on this continent.

 

Yeah Im with you there BigSnag , the 427 SOHC is just one awesome engine with the only drawback being the timing chain but that has been fixed. I mean the side oilers had atleast 425 Hp to compete with a Hemi, and no there was never a DOHC 427. But ya know an unplugged Boss429 would eat a Hemi, and thats production, but people like to ragg on its "rated" 375 hp so im sure that will be the Dodge argument.

 

ford cant touch the hemi for power and speed why do you think chrysler got baned from nascar in the early 70's easy answer too much power nobody could keep up mopar = more power end of discussion

 

Ford could AND was keeping up. In fact they were winning MORE races than Dodge.

 

David Pearson won 105 races most with the Woods Brothers. He did not race the full circuit as did Petty. He won more races than than anyone for the aces entered. Racing the Boss 429 . He and Petty finished 1 or 2nd in so many races. I believe NASCAR stopped them running big blocks so Chevy could compete.

 

Well if Im not mistaken in 1965 the Hemi was allowed to race in Nascar. So Ford introduced the 427 SOHC , just to have it rejected ,Nascar's excuse being it was not a production engine and it would provide an un-fair advantage, but what makes this interesting was that Chevy could run their 427 MK IV which was not even available to the general public much less over the parts counter like the SOHC, so that tells me the biggest reason was the "un fair advantage" or maybe Nascar was still gay back then , who knows.

 

Way back in 69 Ford came out with a New Boss 429. they ran the car for 2 years. 69/70 model years. This car had the highest rated horsepower out of a mustang for over 30 years, until the 03 Cobra which beat it by 5-10 HP RATED. However, those bosses way back when where dyno'd at a bit over 400 at the crank, as are these new cobras. So noone really knows which car had the higher rating

Anyways.

The boss '9 was a detuned race motor. Somewheres I have a lsit of SIMPLE mods to do to bring horsepower up to a nice little level. If I remember right it is.....pistons and cam.....yes jsut pistons and cam...and a bigger carb of course. And we are talking numbers topping 600 hp at least. A swap in heads, as previously mentioned, can net near on 100 hp also. These motors SCREAM. And the only one I know of......has a cracked block because the owner let it sit outside for WAY to long (near on 20 yars now)

Everytime I go to that place I get sad....he has a line of 69/70 boss 302s and 429s that he CLAIMS are not rebuildable.... something like that....unless the frame is ripped in half can be fixed...but alas I dont have the money.

 

Does he want to sell a "junked" Boss 429 car? I would be interested.

 

He might. I really dont think he is willing to sell them at all for some reason. I will talk to him next time I am down there. You mihgt at best be able to get one of the Boss 302s from him. If I had the money I would have all 5 of them there is also a Cobra II back there, not that I care for them but some people do

 

I Am A Die Hard Ford Fan, But Face Facts. Cubic Inch For Cubic Inch, In An All Out Race Engine, Nothing Can Touch The Hemi. N.H.R.A. TOP FUEL, AND FUNNY CAR RUNS NOTHING BUT HEMI. JUST SAW A T.V. SPECIAL BY DON GARLITS ON THE HEMI. HE SAYS THAT DESPITE ALL THE ADVANCEMENTS IN THE ENGINE. ITS BASIC DESIGN IS STILL THE SAME HEMI IT ALWAYS WAS.
IF THE BOSS WAS AS GOOD AS THE HEMI, WE WOULD SEE ONE DOING 315MPH IN THE QUARTER. WE WOULD ALSO SEE IT IN VICTORY LANE AT SOME N.H.R.A. TO FUEL EVENTS. THE HEMI DID NOT START GETTING OUTRUN IN NASCAR UNTILL NASCAR STARTING RESTRICTING IT. THATS WHY DODGE HAD TO GO BACK TO THE WEDGE.

THE ONLY THING THAT CAN OUTRUN THE HEMI IN THE 1/4 MILE IS A ROCKET ENGINE OR JET ENGINE.



DON'T GET MAD AT ME ABOUT THE POST. I WISH FORD WOULD COME UP WITH SOMETHING THAT WOULD NOCK THE MIGHTy HEMI OUT AS THE KING OF THE 1/4 MILE, BUT IT HAS NOT HAPPENED.

I also have never heard of a boss engine that could make 8,000 hp @ 498 c.i.

 

Jimmy,
Let me know. I am dead serious. I would like to get his phone # and give him a call. You can email or private message me, if you want. Thanks.
