STARTER/FLYWHEEL QUESTION
Thanks for all the thoughts AJ/FormS. All 4 of your excellent points do not apply in my case. I ordered a 10 1/2" McLeod clutch from a distributor. In their infinite wisdom I received a scalloped pressure plate that bolts to a 10 1/2" flywheel but holds an 11" clutch disc (I think I've also seen it called 10.9"). (And I told them this is a street car and it is not raced.) I used the small head bolts that came with the kit. You can see from the attached pictures that the clutch disc hit the bolts. I think it is related to the BH being off by .019". I also noticed wear lines on the input shaft in just 600 miles and I had it replaced.
Like I said, the engine builder told me he aligned the BH. He align bored the block and I wonder if that caused these issues. I purchased this block just before it was rebuilt, and it was from a 71 Duster . I checked the BH face for flatness using a dial indicator on the crank and it was within spec. I should also note that I aligned the BH in the 10:00 position, which I thought would help the starter to disengage, not the opposite.
