A few months ago I was reading in a magazine (I think it was Hemmings Muscle). In this article they talked about improving the flow through the exhaust manifold by running a type of abrasive liquid through it. If I remember right it was a '64 or '65 Plymouth that competed in the FAST series. I realize I'm being pretty vague, but does anyone know anyway to improve the flow through the exhaust manifolds. My car is a 1964 Dodge Polara with the 383, from reading on this website is a real bugger to put headers on.
Any thoughts would be appreciated.
