I have a rebuilt 454 (model 1992) and am having timing issues. The dealer has tried to set the timing, but it went form soso, to worse. I am only getting 3200RPM's (before it was 3700) and I am having some problems starting and keeping it running. Is there anything I can do quickly to restore a little of my rpm's without taking it back to the dealer. I know that I can advance the dictributor manually, but what are my indications when idling that I am going in the right direction? SHould I even attempt this without a strobe light? And what should the timing setting be? btdc @rpm?<br /><br />Thanks,<br />Ronald
