if my KJR ever messes up, I'll probably get a non-underdrive UR pulley

Sure, you can select different buckets to set the valve clearance but they do not need periodical adjustment like some types of lifters do. The valve clearance is set for the life of the engine, unless you introduce aftermarket camshafts that change the valve clearances.

I apologize for going OT. To add my $.02, i don't think you would have had any issues had the pulley bolt been tightened to spec per the FSM. The procedure involves angle tightening which most installers don't bother doing. Hope it works out for you.

Its just frustrating because I do all my own stuff. I installed cams in this car and wasnt happy with the tapping from the clearance of the caps. They were in spec but just a little loud for me. So I took it to a well known Z shop and pay to have everything pulled a part and new new caps put back in. This is what I get!

i got UR underdrive pulley. No issues running for at least two years. It was torqued by an impact wrench. The new belts were re-tightened in two weeks to get rid of the squeal.

We have seen this happen on a stock pulley, on a car that was done by a shop in Michigan.The guy purchased the car used, from a guy in Michigan who had the car done there at a half assed shop (Not GRD, and Not Charles's shop) and they never titened the crank pulley bolt, it was hand loose. He also drove it from Michigan like that. To properly install a crank pulley bolt is a PAIN and required 2 people to do it right. The good thins, aside from beating up the softer pulley, the crank should be ok and is internally balanced..So damage was most likely contained to a minimal.
