wanted 4bbl carb and intake

I might be wrong here, but unless you have 340-360 heads on your 318 you have to have a 318 Edlebrock manifold, someone else want to chime in here??

Ideally, yes.

But the larger intake runners on the manifold, can be sealed up to the smaller runners on the heads, no problem.

I am running an LD340 right now on my 302 heads, just fine.
