There are some cast iron manifolds out there for the spec racing classes that would be a good choice for this
pop the hood and then look at the face of the guy when you just handed his ass to him with stock looking engine with stock Gm iron manifolds.i knew a guy that loved to do that. but that was many years ago if you had a street car that ran low 12s with no Nos you were one of the big fish in the pond around here
