I have a 1969 427 4 bolt block casting number 3963512 dated D-28-9 that has one sleeve in it and heli coils in the head bolts. The block is a 4.30 bore size at the moment with one sleeve. The sleeve was put in and cracked the bottom of the cylinder it was in. I have been told at the machine shop it might not be fixable so I'm going to sell the block as is with a set of correct 964 4 bolt caps. $500 and shipping will take it. 330-770-2517 Dennis
