I'm assembling my completely rebuilt GMC 302 and discovered the following; when crank/pistons and valve train are at #1 cylinder TDC the flywheel marking is NOT on the pointer on the bell housing. The pointer is dead on the firing position for 2/4 pistons. Since the flywheel only goes on one way what needs to be corrected? I'm sure it will run in this condition I'll just have to mark the flywheel with the new TDC position if I want to use the pointer as a TDC indicator. Since the engine is out of the truck I can refit the cam chain if that corrects he problem.
