Since there are no timing marks on the balencer I figured I could use the valves to find TDC. I have a stop in #1. #1 Both valves are closed. #8 both valves are closed. #4 exhaust is closed,intake is about 1/2 open. I am thinking that should be TDC on #1. Fireing order is 1 8 4 3 6 5 7 2 Can any of the chevy experts out there tell me if I am right or wrong or if there is a better way to do it.
Thanks, Jerry |

If you have your piston stop in place (TDC) make a mark, then rotate the engine in the opposite direction until it stops again and mark that spot. Between the two marks is TDC. There is as you know and can likely feel a few degrees between the pistons up turn and down turn. This way gets it closer. The truth is time it as far advanced as you can without feeling it whiplash when starting. Normally thats going to get you where you want to be. I know, you really want to know down the the last degree, truth is most pointers are just indicator's at best. Race motors a different story... thats my take on this, I'm no expert (IMG:style_emoticons/default/drunk.gif)
