I see that there is an elastomeric ring on the balancer. Now, can you pull #1 plug and rotate the engine backwards and forwards and locate the piston at TDC? If TDC on #1 cylinder and the timing marks align, your balancer is good. If the timing appears to be advanced, the outer ring has slipped. Setting the timing by the timing mark would then be useless, as it would result in retarded timing and cause your truck to be weak. It could also make it run hotter than it should. This is just another check to eliminate a suspect from the lineup.

I’m quite certain that the marks align. I can check again tonight after work.

The timing seems to be pretty close to where it should be. I’m thinking of buying a new points distributor and seeing if that makes a difference. Could be the lobes are rounded off a bit.

Is it worthwhile spending $200 for an HEI distributor? Are there other parts or special coil I would need to purchase?
