Timing and compression with the 51 cam?
Ok I just got done putting in my new valves and Rude valve train upgrade, I am not lucky enough to have a 28 or a 29 cam yet, so I wanted to make sure my compression and timing sound correct. I got out my dial indicator and put #3 at TDC, I then put the cam locker in, lined up my marks and done. My compression was 120lbs full retard and 155lbs full advanced, does this sound about right? Will the 51 make as much compression as a 29? Also with the valve train upgrade (no aftermarket ECU yet) will I have to repitch to get 8100 rpm again? I have a 15/20 in right now, I have a 14/19 should I install that?
