would anyone know if you could fit an ls6 intake manifold fit on an zz4 crate engine? if not what kind of intake manifold would fit that would give an lot of HP?

 

for the zz4 i'd recomend the performer air gap intake. the LS6, is a no go.

 

You could put a edelbrock rpm intake on it.

 

well, if you're keepin it fuel injected, don't even think about an ls6 intake. that should leave your head, it's for a completely different engine. you should be looking for, if its tpi, an accel, edelbrock, or tpis ported manifold. edelbrock is cheaper, but it won't work for 6 bolt heads, just on the 4 bolt or vortec heads. now, i'm not sure but i think the accel manifold, if found at the right place, is cheaper (about $450), but i'm sure you can find a cheaper place. i'm not sure if there are cheeper manifolds in general, but i don't know where you can get them or who makes them. probably requires research.

 

Or he could go LT1 intake
