I'm guessing you are NOT familiar with Chevelles, right?
A Ram horn manifold, will NOT, repeat, NOT fit on a small block in a Chevelle. That's why Chevelles use LOG style manifolds with REAR outlets.
If a Ram Horn manifold is installed on a small block in a Chevelle, the manifold outlet is IMMEDIATELY, repeat, IMMEDIATELY above the cross member. There is no possible way to attach an exhaust pipe to a Ram Horn on a small block in a Chevelle.
The below ex manifolds are the ONLY factory manifolds that will work on a small block in a Chevelle------------------AND ALL SB LOG MANIFOLDS ARE 2in ONLY.

This is not a SB installation in a Chevelle, but it shows the log style manifolds which must be used on a SB in a Chevelle.
