Has anyone done test on different flathead manifolds. I was wondering the prefomance difference between the stock maifolds that go around the front of the engine, truck manifolds with dual exhaust, cast headers and tin headers.
I have tin headers but never cared for tin headers. I also have truck manifolds for dual exaust. I would like cast iron headers but $300 is to much for me, I'm cheap.
I heard there is no preformance difference until after 2000 rpm. I would like to run truck manifolds on my mild 276ci flathead. Gene
