explain the triangle, circle, and square marks on a 1995 5.7 chevrolet crank shaft timimg gear, witch one do you use to aline the camshaft?
competition cam, .560 lift intake, duration 210, .550 lift exhaust, 218 duration, separation 113 deg. Jegs P/N 249-08-465-8 with a double roller timing chain and gears
I found out, the triangle mark is top dead center on the crank shaft gear, so you line up the camshaft gear mark at 6=O'clock to the crank shaft gear triangle mark at 12- O'clock. Different manufactures will mark certain degrees on the crank shaft gear, but you need to know witch one is top dead center. Some or most only have a dot at TDC on the crank shaft gear.
