68 casting#

Help-
I've got a 68 vette with a clean pad. casting # 3914660
where the date should be is convt or convi (not sure)
the car is a very early build-10/67. Certain reference books say this is correct for an early 68, others do not mention this #. Any help would be appreciated. Thanks-Tpic

Look at the same spot as the casting # on the opposite side. Should be a casting date there.

Look down on the right (passenger) side of the block above the oil pan. If you find the casting date there, this might be a McKinnon Industries block.

Conv 1 means it went down conveyor 1 when it was cast. Took me 25 years to learn that.
