Exhaust Manifolds
 
The headers I have on my 70 were bought in the early 70's. Not sure of the brand. I was thinking about going back to a Ram horn style manifold. I'd like to use the 2-1/2 ones. Do the manifolds have to angle back for out trucks or do the straight down ones like on the corvette work?

I think if your small block is in the forward position like a factory V-8, the angled ones would be correct. If in the rear position like a 4x4, the straight dumps would be correct.

4WD goes straight down. I believe 2WD is angled.
