I am looking at a '66 NOM Vette that is said to be an original 427-car. I have a correct '66 427 Corvette engine set-up looking for "the right car". I have been told that some of the indicators of a true midyear big-blocks are: Original AZ code big block rear, Rear sway bar, seven leaf springs, 80 PSI oil gauge, tachometer redline, hood support on left side. Can anyone tell me if these are correct and if there are other signs that I can look for in order to reccognize an original midyear Big-block?
