If the flange has a crescent...

...If the flywheel flange has only a square notch on it, then it's a 391, if it's got both a square notch and a large crescent (football shaped) cut, then it's a 330/361 crank.

If the block will fit a 15/64" drill bit shank between the cylinders in at least one spot while probing around inside all six core plug holes, then it's likely a 330 block which can probably me made into a sturdy 390 block. If the bit will not fit at any location than it's likely a 361/391 block, probaby good for an eventual 428-style boring, sonic permitting.
