Unusual engine photos

Pete Aardema has had his fingers in A LOT of engines/modifications.

Here's another oddity from Harry Miller, two 151 cu. in. blocks adapted to a horizontal crank case for an opposed flat 8. These photos were in Old Car Illustrated, March 1979 and I could find no other info on this engine.

 

Bill Harrah not only collected the Cl***ics, he also had a large number of old engine conversions on display, here are two articles featuring early modified engines.

 

Early race engines came in many forms, 4 bangers up to 16 cylinders, flatheads, overhead conversions, cam in block, SOHC, DOHC everything was tried in the quest for speed. The rarest here has to be the Peters midget car engine.

 

Love those old magazine articles, thanks for posting. Names are familiar & try to remember who Dean Batchelor ( road & track? ) & Neal East known for.

 

You’re correct about Dean Batchelor. Neal East is probably best known for a series of great ‘32 Fords that he owned, but he also wrote for a number of magazines, collected automotive memorabilia and in his later years moved to Colorado where he opened Colorado Car Books which is long since closed.

 

Batchelor was a hot rodder before he became known for his involvement with sports cars. He was an early customer of Alex Xydias and went on to partner with him in the Xydias & Batchelor Bonneville streamliner. He became editor of Hop Up magazine in 1952.
Batchelor lobbied for a long time to get a Hot Rod cl*** at the Pebble Beach Concours. Sadly, he didn’t get to see it happen. He died in 1994 as he was finishing his book The American Hot Rod.

 

UPDATE: I found a few details on the Miller opposed eight-

 

Yeah, just another SBC, but the genesis of this one has Duntov as it's originator. I'm not sure what became of the project as Bill Harrison intended.

 

There MIGHT be one of those in Speedy Bill's museum in Lincoln.

 

That great article on DOHC Chevy was in 1984. What happen to it/them? What is history since 1984?

 

"" Bill Harrison, who developed the Hemi rear end, now running in many of the nation's most compe***ive sprint cars,"" Hemi rear end, never heard of it?

 

Iz zat like a rear end with hemis ??! I've had one of those..........

I hadn’t heard of it either but I googled it and found out that it used Dana 60 gear sets that have 9 3/4” ring gears, much stronger than the 9” Ford gears.

 

From our pantheon of on-line knowledge
HEMI Quick Change Rear End | The H.A.M.B.

 

Here’s an engine I ran across looking for info on something else. Some here have heard of Dave Crane, RIP, Dave was a drag race historian/collector with an incurable p***ion not only for engines and parts but cars too in his private museum.
How about the very first OHC conversion on a 265 Chevy?Built by Bill Quigley when the SBC was relatively young somehow Dave became the owner. I don’t know for sure but it may be in the Museum of American Speed in Lincoln, NE now.

 

Here’s another small block, this one is a Chevrolet Engineering exercise.

I wonder if the plan was to use the 3-2 Holley intake on the Camaro? The engine has a mix of parts, ‘67 and later exhaust manifolds, AIR pump and plumbing and 327 style valve covers. I always liked those covers but the ‘67 302 used chromed Chevrolet script pieces.

 

Definitely planned for production since it had a A.I.R. pump on it and the pvc system.

 

That's the L-70 option and only about 6 manifold were ever produced... It was also pictured in a 1967 repair manual with all the part numbers but was canceled pretty much from the get go....

 

If the OHC Chevy engine is not in Speedy Bill's museum it's twin is. And the 3X2 manifold IS in the '67 Camaro ***embly manual with a big X through the picture. It waas proposed but never used.

 

No words about miki Thompson DOHC???? Is that early version of ford Indy engine? Other pic rear engine Chevy road racer



Thompson DOHC

 

It is a pushrod engine., very complicated valvetrain.

 

First photo is M/T’s three valve SBC, two intake , one exhaust. Second photo is a Pontiac engine, identifiable by the valve cover shape. No idea what type of car that’s in but the photo is of the front of the vehicle.

 

Trying to remember; maybe someone can help. There was a British (?) engine maybe motorcycle that had 2 pushrods off cam to rockers. One rocker opened intake , other rocker pushed another pushrod to another rocker arm to open exhaust valve helped make a hemi head. Lots of monkey motion. Result each cylinder had 3 rockers & 3 pushrods. Do not remember if it was a winner or - - -

 

Mark Dee’s came to Bonneville in the 90’s with his 314” Offy powered champ style roadster.. I don’t remember his speed!

 

You are thinking of the it was Italian Ducati desmodromic engines that have 2 push rods per valve, 1 to open the valve and 1 to close the valve means absolute control over valve float.

 

It sounds like the pre-WWII BMW sixes, production of which was continued by Bristol after WWII.

The early iteration of the Alfa Romeo V6 of 1979 used short cross-pushrods of that kind off single overhead cams.

 

Desmos sound awesome. There used to be one that went past the house often in the summer.
