exhaust manifolds

Will 330 exhaust manifolds work with/on 455's? I read somewhere that some 455's used small block manifolds. If so, any loss of low end torque? Thanks to all.

I would think that the loss would be on the top end. That is if the 330's are smaller.

another exhaust question

My real question is, which factory exhaust manifolds would fit/work the best in this application? Thanks to all!! Main interest is low end torque nothing over 4500 rpm.

I merged your 2 threads so you don't have duplicate answers. If want to go with aftermarket manifolds, check out Thornton
