Intake/Carb combo (C3 454/270HP - now 480HP)

Carburetor swap. I have been told that there are no after-market intake/carburetors combo that will fit under the original hood. I looked into JEGS and Summit and spoke with their tech dept. Neither came up with a combo that works.

Has anyone found something that works?

Thanks, Bill

Do you not have a big block hood?

Here is an interesting thread, note post #6.

Also, put "carb and intake for 72 corvette" in your search engine....

The BB hood shows in the picture. 

Don't know if this is any help but "The Toy", the '70 convertible I owned for a bunch of years, was built in early February of '70 with the base 350ci.  When I bought it in 2000 there was a Holley carb on it instead of a Q-jet.  There was enough clearance under the stock hood to add in a few layers of Mr Gasket stuff to help insulate the carb from the manifold (which solved the heat soak issue I was having).

He has a  big block.

The BB sits higher. Even though I have a BB Stock Hood, I was told that the after market intakes are taller (better air flow/draft) and I would need to change my hood for that. Not changing the hood. I just spoke with the guy who is building the engine for me and he said he would re-jet and make the stock Q-Jet work for me. Thanks for all the input.

Didn't realize there was that much difference in size between the "Mouse" and the "Rat".  Glad a solution was worked out.

Hey Norsky, Been a while since I've heard that moniker for the SBC and BBC. It goes back to early wrenching days and dirt tracks. Showin our age my friend!
