i am also wondering if aluminum manifolds will give my 454 (300hp) any or how much more hp. stainless steel headers on my wish list....but a little too pricy for me. there seems to be alot of companines that make "performance" exhaust for less money than the ss headers. Bill 22zx

Little to -0- gain! But you being in fresh water they will last a long time and also lighten the back end up a little, they are also much easier to handle then the iron monsters.
