The eng. block casting code is one of the best ways to I.D. that eng. This cast no. is usually found at the rear of the block on the left or drivers side on top of the bellhousing flange. Also write down and post the eng suffix code which is stamped on the flat machined block surface pad located on the front RH or pass. side of the cyl. head. This suffix code will consist of several numbers and 2 or 3 letters at the end. Hope this helps.:anim_25: :bowtieb:

The '56 Corvette block was identical to the Flint passenger car, truck, commercial, marine, industrial and service replacement blocks. The only way you can positively identify an original '56 Corvette block is if the pad stamping on the front-right is original, not milled off, and the original stamped characters end in GV, GU, GR, FK or FG. If it's anything else, or if it was milled off during rebuild, or if it was altered, then it's not a Corvette block. It can be built to be one, but you won't get a Corvette price for it.
