Setting Big Block Idle & Total Timing
I just replaced the timing chain on my 1973 Chevy C20 454 and when I hooked up my timing light and vacuum gauge it was on 14 degrees ATDC and a steady 22 HG but that's pretty much where they were before. Don't get me wrong the truck runs good I just thought I'd see more response. I probably put 5-10 miles on it a week but I start it every couple days anyways. Is setting the Total Timing that important for a non-daily driver and does Total Timing affect stop and go driving?
