351C 4V heads
 

Where can I get a dual quad, low or medium rise manifold for this engine. I have tried Offenhauser, Edelbrock etc. Any info would be greatly appreciated

The only dual anything manifold I've seen for the Cleveland is a 9 inch tunnel ram somewhere in a Summit catalog.

I like to have some HP under the hood without cutting it. Thanks for the info

I'm pulling about 330 horses out of our Cleveland with a 600 Holley on a factory manifold. Ours is basically stock but I know a feller here in Amarillo who's pulling in the neighborhood of 650 horses at 8500rpm with a single 900 holley.
