Also I was able to borrow a nice digital timing light with a built in tach. I adjusted the POT switch I wired into the M- and M+ terminals on theback of the tach to match at 4000 rpm... then when I check it back at idle, it was 400 rpm off! actualy RPM was 750 and the tach said 1150 RPM ARGH..... So thats a big no go. Guess I'm just going to swap a V6 SR5 cluster in there and be done with it! Anybody got one for cheap.....
