Wondering how well manifolds would hold up running a set of twins on a 427 lsx build making around 1300 at the motor? I like the fact they are tucked in tighter than headers but dont know the they will hold up to the power and flow enough! Are there manifolds that flow better than others?

There are lots of manifold builds that do over a thousand hp on here.Some creative searches will turn up some info for you.The ones that always come to mind when I think of this is ohio boys and mike brown,very succsessful truck manifold race cars.

The Ohio Boys went around 200mph with production truck manifolds..... I'd say they work just fine

So are there manifolds that have bigger ports to flow better?
