Piston Scuffing

BTW Hammer got me covered in 2014. with new kit and it works good still 2023. Aron is right for timing advance. Motor is performing better on 2.nd and 3.rd curve ,but 4th is still good and the safest. 1st curve ping , 2nd curve ping under load ,3rd is ok but it can make hits to your drive train cuz if explosion occurs under load cuz of early timing it'll hit valve that transfer that hit on rocker arm than on pushrod and cams eventually.
