Re: L-72...AMA specs NEEDED!!!!
OK, I think I have half-way figured out my deck height problem. As best as I can tell, the only engine that Chevrolet worried about the deck height on was the ZL-1, as they were blue-printed from the get-go. In the AMA specs, I found ".000-.010" for the ZL-1 piston-deck clearance, but have found nothing for my L-72. So, I took and figured the stack height for my L-72 (1/2 the stroke+piston compression height+rod length) and subtracted that from the block length of 9.80, and you get .030 clearance. So, that is probably going to be the number I go with.
But, now a couple of questions. Stan, is the gasket you mention is correct for the L-72 still available from GM? Or, would I have to get one from Fel-Pro? Would anyone happen to know any specs for the correct gasket (like bore size, volume, etc)? Also, would anyone know the correct gasket for an LS-6? Would it have also used the steel gasket?
