I just picked up a BBC. Casting number 3855961, head casting number 3872702. Date code L-28-05 Front number T01121VR. The bore is 4.25 but the casting number says could be both. Can anyone help me identify this motor as to what it might have come out of. Is it a vette motor? Any help would be greatly appreciated.

only 427 and 454s run a 4.250 bore, it is not a 396
