427 Block Question

[Enoch]

Without looking it up I belive that is a Corvette designation for L-88 so an August dated block would be for a 68. Whats the casting #'s 351 or 321? It should be a 4 bolt main also. Could you post the full Tonowanda stamp.
Rich.
It should have 842 aluminum heads.
If there is no vin it would be worth quite a bit to some one with a 68 L-88 Vette with the wrong motor. Also that is what Motion put into some of thier cars, so if anyone has a Phase III 68 anything that would be the correct motor fo it.
