New subscriber here and need some help. I put a 350 4 bolt main short block in my 64 vette about 15 years ago. I didn't have the engine accessories, so I scrounged brackets etc all from junkyards and swap meets. One of my problem areas is with the harmonic balancer. Its an 8" and is needed (I think) to keep all the belts aligned. The timing line doesn't show up on my timing light. I am not sure what to do. I know there are tapes and other stuff to apply to a balancer, but would rather buy a new or remanufactured unit.
