A 4.600 bore BBM aint gonna leave a lot between the bores on a 4.800 BS block...If you really want 4.600 you need to buy a 4.840 and a set of 600-13 heads and still roll the dice at least you leave .240 between the bore edges so .120 per cylinder.

BTW what block is Sherman racing engines selling?? Assume it is the same one Chicago connection and others are selling?
