Ive just bought a second hand engine which has piper vernier pulleys and the cam timing has been set to the engine builders spec.
The problem ive got is i want to change the pulleys,possibly to cdf racing ones and am wondering how accurate the markings are on the pulleys?
If its a case that the gauges on the pulleys are not good enough to set the timing on can anybody point me in the direction of a cam timing guide?i know the basics but need a step by step guide to follow.
cheers
