How exactly does timing tape work and exactly how do i time my engine, I am going to buy a expensive timing light from kragen, and take it back when im done with it. I want to do my total timing, i think its supposed to be about36-38, around 2,800-3,00 rpm. Im a little confused about the whole thing, I know how to set initial easily though. Also what don't you touch when turning the distributor when adjusting timing. I have msd setup(dist.,box,coil) and shocked the hell out of myself, jumped up straight in the air, one time while adjusting timing, would like to not let that happen again!!!
