I've got decked heads and a BIG cam, plus bolt ons, but at 6,000 feet, so take off 20% of power. Would have 570 rwhp at sea level, only 470 here.
I'm gonna back off 4 degrees of timing (24 before, tops, will run 20). Question: Do you pull all 4 degrees throughout the band, or pull less out at lower rpm's??
I was running NGK TR6's at .040", gonna run TR7's (non projected tip) at .034".
I'm gonna put her back on the dyno for tuning, set the A/F to mid to high 12:1.
Anything I'm missing?
