318 top end build

I'm running a 318/904 in the Demon. 69 Cuda 440 has given you a good shopping list. I'm running, 302 heads, a 625 cfm AFB, and a little more cam.

I think the 500 cfm Eddie will work fine. IMHO the key on the carburetor is an air valve secondary. This feature allows the secondaries to open when the engine is ready, reducing bog.

When you're getting gaskets, make sure you get soft, thick intake gaskets. The thin metal ones that come with most gasket kits do not allow the manifold to seal properly resulting in flooding when the radiator is filled.

If you're running a Torqueflite, you'll need to make a provision for kickdown. Lokkar makes a kit that is widely available. If the hot rod look of it puts you off, check out Bouchillon Performance. The install looks very factory under the hood. Works great. I've installed two on different cars with no problems on either.
