Now, all you need to know is how many degrees After Top Dead Center (ATDC) the crank is. You can use a timing tape, or mark and measure the balancer. You could even put a white dot on the damper at the 0 line on the timing tab, and use a dial back timing light (if it went to ~120 degrees ATDC to measure a ICL of up to 120, or use #4 wire and do some math 60 BTDC ) to find the amount of degrees the crank is ATDC.

Kinda illiterate to this,lol.. so can u explain easier? also what about the flex in the lifter cup if there bled down? wont this be inaccurate ?.. My balancer is marked the first 60* i believe then every 90 after that.. Its professional Products SFI one
