Camshaft endplay, bad thrustplate?
Finished the short block for my '69, and moving into building up the long block, I have run into a problem.
Put in the cam and timing gear, I find the end play is out of spec. Pontiac calls for 4-7 thous., I keep getting 12-13. So I pulled everything apart and the aftermarket thrustplate I recently bought from Ames is ~0.008 thinner than the plate that came off of the engine. Has anybody else had this problem? Is there any other reason that cam could be shifting around in the block?
Always possible I have done something stupid, too. Doesn't seem like there is much to go wrong in this situation, though.
