Dohc

WOW, that's some interesting reading there. In the application they talk about aircraft applications for this. Because of lighter weight and smaller size than a gear train driven DOHC would be.
Very interesting how they figured out cam timing with different spline counts on the shafts and bushings.
and an intercooler for the supercharged ones, too.

Thanks for the link!

I was thumbing though one of Don Montgomerys books and they have a section of OHV conversions for flatmotors, might pay to check it out. I justs cant remember which book it was as I thumb though them so regularly that they all blur into one...

I think it was 'Hot Rods as they were'

some cool info here though

 

I have a HOT ROD issue from the mid-60`s here somewhere that features either a SOHC or DOHC aftermarket conversion for a Small-block Ford.

 

I wounder what one of those 1100 cubic inch Ford V8s would look like with 3 twos and Zoomies?

 

Thanks for all the tech and info guys.
These post(engine tech and engineering) are my favorite to read on the Hamb. I search alot and don't post to much. I enjoy to read about this sort of thing.

I actually found this old thread while I was searching for info on indy cars and esp the NOVI. I have read guys talking about how it sounded. Does anyone have a link to a video so I can hear it for myself?

 

"Mac" McKellar, engineer for Pontiac in the late 50's and through the 60's designed a 421 SD DOHC engine in mid year 1962. Pontiac built 4 of these engines and took them to different test facilities within the company. When the race ban hit GM in early 1963 these test facilities were told to destory any and all race type products. These engines were long thought to be destroyed. In the early 90's they found one in a back warehouse at GM. They presented it to Mac as a retirement gift. He hadn't seen the engine in over 30 some years. He did end up putting it in his '63 Grand Prix.

 

A very short (7 sec.) Novi sound clip at the bottom of the pic./sound gallery here: http://www.milleroffy.com/

 

If anybody is interested I have a Maserati DOHC V8, with a T5 trans. adapted to it.

 

Might be a little late for ya, but i know that some of the shelby mustangs had an overhead cam engine, it'll cost ya a pretty penny to dig one up, but it'd be a ford engine

 

I've just spent an hour trying to find a copy of Motor Trend ( I think) from around 1954 with a photo on the cover of a Desoto TWIN OVERHEAD CAM HEMI...The engine was painted Yellow and was run on a dyno with the cams driven by chains. Sorry I could n't find the mag,but it's a lead for ya..

later Engines have to include the AMG DOHC engines that the german Mercedes tuner AMG built in the late 70's to mid 80's, years before Mercedes built it's own DOHC engine the M119.
This is a 6.0 liter AMG V8 ,around 400+ Hp.Not to shabby for 1982

 

Some years ago(70s??), Citroen built a line of their weird looking cars with a DOHC Maserati V6, appropriately known as the Citroen-Maserati. Ugly car, beautiful engine!.... Saw one in an Indy junkyard in the mid 90s, which eventually disappeared, and saw one installed in a replica Novi Indy roadster, built here in Indy, now running at vintage events in California..... Think I'll google up Citroen-Maserati and find some more details.

 

Didn't Moser build a DOHC conversion for the SBF?

I'm sure I saw one in a magazine article installed in Tom McMullen's 2nd attempt at his flamed Deuce roadster.

Cheers, Glen.

 

Citroen SMs used a V6, shared with the then current Maserati Merak. Horribly expensive to rebuild, even if you could find one. The big sister to the Merak - the Bora - used a similar V8 motor.

 

museum of american speed <--- good resource.

I have a 1976 Alfa Romeo Alfetta GT that I bought for $300 2 years ago to run in a project but have decided to keep it together. motor is a 1.6L DOHC all alloy (including a finned sump) dual Dellortos and factory headers.

Alfa Romeo Montreal form the seventies had a Formula one derived four cam V8, with 200 hp.

 

Sounds cool,I would like to see pics of it.

 

Never heard of or seen one till the new GT500's.

 

The engine was derived from the Alfa 33 Sports Racers.

 

Chrysler built one (rumors of two) DOHC 426 Hemi engines to counter act the SOHC engine Ford was developing for NASCAR in @ 1964. When NASCAR outlawed the Ford engine, Chrysler stopped with the DOHC Hemi.
The Hemi produced @ 800HP on the dyno during preliminary testing, but broke it's magnesium lifter guides? I have the article somewhere in my MOPAR archives..."the DOOMSDAY Machine".....I can get more details on it if wanted....pretty cool stuff......

 

That´ll teach me to believe what I read in classic car rags!

 

Hemming's Classic Car magazine lists the 1921 Wills-St Claire V8 with single OHC in it's list of the 12 most significant engines of all time. There are some neat engines in the article. The '32 Ford V8 and '49 Olds Rocket are pretty far down the list, to give you an idea of what kind of engines are listed.

 

there was a post about a guy who put one in a mustang, did that post ever get unlocked after the farq crash?

 

Ford Indy Cammer...

 

SOHC

 

There are some clips on Youtube of the engine running.

 

Though a SOHC this is still one of the coolest engines ever built, Sir Jack Brabham's Repco-Brabham V8.

Here is a Miller V16 with DOHC.

http://www.rickcarey.com/Catalog Descriptions/RM LA 052502 Miller V16.htm


Stutz had the DV32 - Dual Valve 32 total straight eight from 31 to 35. Looked like a Duesenberg Model J in 3/4 scale. Was actually a better engine pound for pound.

 

More 1943 Ford V8

 

Nope, it looks like what you said was true as well...

http://en.wikipedia.org/wiki/Alfa_Romeo_(Formula_One)

"Alfa-Romeo briefly returned to Formula One for the 1970 and 1971 seasons with a V8 engine based on their sportscar unit. "

I did not know that... I thought they went to the 12Cyl Brabhams right away, when they got back into GP Racing.
