Dohc 427 Fe
Was talking to a buddy about rare cars when he mentioned 427 SOHC motor. I mentioned the DOHC 427 (developed around 1967) & he said he never heard of it. I checked out the net & couldn't find any info on it. I don't think I'm going senile yet... Do any of you remember the DOHC?
-
Hot Rod Magazine had a number of issues devoted to engine development by the manufacturers, including many engines that never made it past the R&D stage. Maybe you are recalling one of those.
Chrysler built two DOHC Hemis. One was destroyed. The other is in the hands of a collector, who I believe put it into a Super Bee.
-
The engine that went into "production" was a SOHC, meaning it had a single cam in each head. Not sure if you or others think in terms of there being two cams on the engine meaning it's a dual overhead cam. Normally that is in reference to the number of cams per head.
Now, as to the senile thing, we'll need to keep an eye on you to determine that.;) One good thing though, when you're senile, you meet new people every day...............and they already know your name!:eek:

Whoops.........forgot to attach the pic showing only one cam on the head. Now about that senile thing........................

The SOHC, or "sock Ford", is of course legendary, but pricey nowdays. I would not be suprised if the factory prototyped and tested a DOHC, but no production version was made that I recall. I always tell people that "I always tell the truth!....at least as I remember it!" :-) (does that sound like an excuse for senility?)
I sold most of my 5000 magazines, including those Hot Rod engine issues, or I would research it for you.

I wasn't even considering the smallblock Indy engine, but that was obvisously a DOHC. Whadda ya think, Dyno?
-
Denny those are some really cool pics. Thanks.

Those are some awesome pictures. May I ask where yall got them from? I would really like to know more. Would any one happen to know any ifno about Fords 3.0 liter indy V8, or would that picture of the 64 Indy V8 happen to be that engine? Please let me know. Thanks again for the pix, I have been wondering what that 427 SOHC looked like.

Thanks for that geocities link Bob. I am really interested in learning about rear motors like that. I was also wonder if anyone has ever seen any pictures of the DOCH hemi that HOTRODPAINT had mintioned. Thanks

I found this about the DOHC Hemi from www.allpar.com/mopar/hemi/hemi.html
no pictures though
Dual overhead cam HemiA 426 dual-overhead cam Hemi was actually produced - two of them, in fact, and both were made in 1964. The DOHC Hemis were made to counter Ford's response to the 1964 426 Hemi, the 427 SOHC, but when NASCAR ruled against Ford's engine, there was no need for the overhead-cam Hemi.
Neither of the DOHC Hemis were ever placed in a car; one was destroyed, the other moved to the Kansas City area. (source: Muscle Car Review. Thanks, Stéphanie Dumas.)
An article by Tom Shaw in Mopar Muscle went into considerably more detail. The DOHC Hemi was project A-925, and it would need to be much more powerful than Ford's SOHC 427, but still rugged enough for racing - and able to conform to NASCAR's rules. Two possibilities were seriously considered, according to Shaw - one using two cams positioned between the heads, in the "valley;" four valves on each cylinder were operated by lifters, pushrods, and lifters. This expensive setup was considered to be a contingency plan and was never actually created. Nearly as ambitious was an engine with aluminum heads, dual overhead cams, and, again, four valves per cylinder, with pent-roof chambers. (Chrysler had been working with four valve per cylinder engines for a never-completed Indy run in 1963.)
The dual-plane intake manifold had eight runners per side (Chrysler was heavily into efficient and innovative intakes) and made of magnesium - but designed for a single four-barrel carburetor, as required by NASCAR.
The cams were driven by a cog belt, using external cog wheels at the front of the heads. Because the cams were directly above the valves, valvetrain mass was low, so the engine could rev high - a 7,000 rpm redline was specified, high for the era.
Shaw noted that no DOHC Hemi ever ran under its own power; they were driven by an electric motor to check the valvegear functioning. Research stopped in 1964 when NASCAR banned the SOHC 427 and Chrysler's own race Hemi. One DOHC Hemi still exists.

Thanks for the input everyone... I knew I wasn't dreaming. It was the DOHC developed for Indy that I remembered..... things tend to get a bit cloudy with age ;)

Denny that is a great link. THOSE HEADS ARE HUGE!!!!!

I would post a picture of my Cammer but I can't figure out how ! I can time my cams but I can't figure that out !
Ford did make a 3 valve "calliope" 427 for lemans that had an over/under cam in block arrangement. It apparently did not race when displacement rules changed, but there is a picture of a comlete engine on the cover of June 68 hot rod. (I don't think its an FE it just happens to be a 427)
-
Dennyw, according to an article that I read years ago, the collector who owned the second DOHC Hemi, put it into a '70 Super Bee,. His reasoning was that if it had gone into production, that would have very likely been the first candidate to receive it. I'll post a picture of a model I built with one. Ironically, it came with a '70 Super Bee kit.

I Know, I know it's just a model....but I'll bet a few guys on this list still build! :-)

This isn't the best picture and I believe it was at Irwindale in '66. I believe Lou Baney owned the car, but the driver was Don Prudhomme. I don't believe they campaigned the car very long, it just wasn't successful.

alot of people hardly know anything about pete robinson he had a degree in mechanical engineering and was also one of the 1st racers to start using "wings" and "air-foils" on his cars. he also ALWAYS had some of the lightest cars around. take his early blown small block car in about 65 i do belive was like 890 wet it was super light didnt even have a chute until he got yelled at by someone so he went and got one they say it was about the size of a hankerchief! btw he won that day AT INDY kickin all the hemi's butt's he also did pretty good with those cammers even connie kallita tried them for a while but after ford dropped ford factory support pete was about the only guy out there still using them until his death.
