Thread: What headers should I run for my 65 chevy truck?

Tweet

I'd use cast iron factory manifolds to insure clearance around starter, steering, filter,fuel lines etc----------you can get them ceramic coated for appearance----headers won't give you any performance/milage advantage and in fact will probably knock it down in most rpm ranges that you drive on the street----and then there are the burnt plug wires, increased under hood temps causing vapor lock, difficulty to seal, spark plug change difficulty----------list goes on and on






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
