I should have at least tried to check timing before removal of my current tab but like an idiot i didnt and just removed it thinking i could used a piston stop but it doesnt hit the piston hard enough to trust it due to the angle and i cant get a reading with a dial indicator that i can trust. Engine in truck and fully assembled, truck runs great and is at 34 or 36 total timing but i dont remember honestly.. really want to confirm before i put the 100 shot on it.. not sure of what to do at this point.. i dont like guessing or pulling heads off.. any thoughts?
A piston stop should stop the piston so I'd try again. Also, you don't want it to hit the piston hard either anyway. Put stop in there until piston hits it. Then place your mark on the balancer. Reverse direction until piston hits stop again. Put your other mark on the balancer. The middle istance between those marks gives you your TDC.
