340 vs 360 confirmation

You young Bucs need to quit smoking that CLEAR. It is melting your brain. Headers are always an improvement over stock manifolds. I never lost a race against a car with stock manifolds and one of my early A-body 340 Duster s had flattened 2 pipes on drivers side and I still blew the doors off cars with stock manifolds and that included the street Hemi cars of the late 60 s or early 70 s.
