Hi all, need help. I think my cam timing is out half a tooth (one tooth on the crank). is it possible to fix this without pulling everything to bits again and would this cause a huge power loss as well as popping from both ends? idle's fine, gradual rev increease smooth as, open it up at any rev and keep it open, pops crackles and other noises not associated with a healthy setup.
Current engine specs- .030 over pistons, head shaved .030, mild porting with pollished exhaust. cam is 66 18 with a duration of 195 deg @ .050 ( is good, kicks in at about 3000rpm and all the way up to the rev limiter). std comp
would be gratful for any insight.

has the motor just been rebuilt?, if not then i would doubt the timing would slip a tooth with out busting something serious. I would check you ignition timing and the dizzy cap. if they start tracking inside the cap this sort of thing happens. Had it happen to a 300e just a fter a water blasting. Thought it was somethin serious for a bit. The popping at both ends means there is spark at the wrong times.

Has been rebuilt, so the timings my mistake. Though I hadn't thought of the dizzy for faults, to busy looking for other probs. will give that a look in the morning.

Cheers.
