I am looking for anyone that has experimented with vavle timing? Either advancing or retarding cam timing. If so what worked and what didn't? I have my cam advanced 4 degrees, I have no power above 4000 rpm. Would retarding the cam help with the top end power? Any help would be great!

put it straight up and see how it runs. yes retarding it will help top end but you will lose some bottom end.

get a progresive timing light and ajust it from 36 to 38 degrees at 3000 rpm that is a safe place it wont run hot or be hard to start.this is what most cam manufacturers recomend.

It depends on a few different things like car wieght, track size, what cam you have, lift, duration and lob center are all variables when advancing or retarding your cam. If you bought your cam from a manufacture like isky or crower you can call thier technical line and usually get the information you need.
