Rare small block chevy intakes

Zora Arkus-Duntov’s CERV I, the Chevrolet Experimental Research Vehicle .

When first built in the early ‘60’s it had a well built 283, but later the 377 engine was fitted and other components were changed also.

 

CERV II I believe, one of Duntovs' "skunkworks" projects.

Edit^^^^^^what Fordors said^^^^^^

 

Did it run?

 

Absolutely, there was an extensive magazine article written at the time, it might have been in Hot Rod, Sports Car Graphic or Motor Trend. Duntov drove it in testing and I think it was entered in a race and driven by someone else.

Edit- It was never raced, it only made exhibition laps at some races.

 

Early lakes racer and engine builder Bob Joehnck knew Vic Edelbrock Sr. and Vic Jr. In 1965 Joehnck convinced Vic Jr. that there was a market for a SBC aluminum four barrel intake. Here’s a Joehnck MK-1, Vic Jr. cast those for Bob to sell at his shop, and that was the genesis of the C-4B.

 

A little sidetrack.............Been looking at some history on Duntovs' "lightweight" engine program, seems this was untilled ground, new technology to cast aluminum heads and blocks, I sure wish I had a half dozen of those engines from Zoras' various programs.
Apparently to save weight they tried running without cylinder bore liners, valve guides and seats.
Spotted an oddity (for 1962/63) on this aluminum head, anyone else notice it.
Hint, it's not the guideplates/studs.

Exhaust ports stud location is at a angle on the end ports.

 

thanks!

 

Floor inside of head has been cast in way just for intake ports / runners & coolant p***age.
Skeleton cast .
Weight saving & need for push rod guide plate .
I think for the angle outer mount
was done for strength & porting enlargement

 

I see posituve valve seals.
Wonder how early those came out.
Thought thise would be wuite a bit later.
