Anyone know the sizes of the diameter of the cam bearing diameter (i.d.) for the 239 EBU versus the later Y blocks?

For the 239/256 engines, cam bore diameter is 2.182” while for the 272/292/312 engines it is 2.058”.  The bearings themselves will be slightly larger than this to maintain a press fit.
