I recently went to an end of season test and tune. I had been running a total advance of 36 degrees and reduced it to 32 degrees and the car ran about 7 hundredths quicker? I then reduced it to 28 degrees and it picked up a couple more hundredths? It is a lot easier on the starter when it's warm and at 28 vs 36 also.
I would like to know what others are running for total advance on their 500" R/B engines?
Thanks! MJ
