Aluminum Main Cap install--PITA
Just wanted to share last weeks work menu. I've been line-honing a little longer than line boring and the two go hand in hand but line boring is seldom necessary. However when installing aftermarket caps with .100"+ to remove line boring is an absolute. Before I was capable of this operation I had to source it out--and No joke, I NEVER EVER received a perfect job back. There was always some issue with it. I once sent a SBC with splayed caps out for line bore and it came back with one of the caps backwards!! I had to machine a bearing tang (notch) into the opposite side to correct it. The worst one was a SBM (408) that was line bored .017" incongruent with the decks front to back! I only paid $600 19yrs ago for that one. The pictures here don't show the 16 hrs that I can't fully charge for which sucks but that's what I get for wanting to nail the dimension 2.9423" . I don't think I'm going to accept aftermarket cap installs anymore--it's just too much time I don't have. J.Rob
