302 chevy SB with three duces
« on: July 12, 2015, 01:10:27 AM »
I was looking through a Holley carb book recently and found a picture of a 302 chevy small block with three duces sitting on top of engine.  Has anyone seen something like this before???
Thanks

That wouldn't be a factory setup, but I do recall reading something years ago about Smokey Yunick experimenting with a tri-power 302 SBC. Are you able to post a picture of that book image?

A factory 3 x 2 small-block set up got close to reality.

Check out page A11 in the K19 section of the 1967 Camaro Assembly Instruction Manual. Was to be the L70 option, probably for SS350. Many years ago an intake manifold for L70 was found with a '0-' casting number.

As I recall, either Edelbrock or Offenhauser made a 3x2 intake for the small-block Chevy that used Rochester 2GC carburetors; I remember seeing them on various shoebox Chevys in the late 50's.

Offenhauser used to sell a 6 pack carb top plate for their cross ram intake manifold, think it was made for a set of 2300 series Holley carbs.  Probably can still get it if you can find someone that sells the Offenhauser Cross Ram.

FYI " Almost all of Chevrolet experimental parts carried a "O" or " L" casting number" CBTN's page 161.
