Possible scenario: If the car has 074 open chamber heads, and if 12.5:1 closed chamber pistons were used would that not put the squeeze around 11:1? I feel if the car is legit then the owner should have no problem with sharing all the internals of the engine. Dates and Part numbers on the heads, Piston compression ratio and part numbers, Is the Deck surface original where the stampings are. Does the vin number on the trans match the same font as the engine deck? Also I agree that if he could get a hold of Calvin ------ of Hatboro PA. he should do everything to get a hold of this original owner. I for one would like to get this myth dispelled once and for all. LETS GET THE FULL STORY!!!!! Theres more to tell than the POP
