Nice standard bore 4-bolt 3963512 block dated 12/69. This was originally a warranty replacement on a 1967 427 Corvette but would work just as well for a '68-69 L-72 or an early LS6.
Never bored, decked, or repaired in any way. Has been cleaned and magged. The cylinders are all around +0.004" so it should be bored in my opinion. $2750 and I can bring to MCACN if prepaid. |
