I am trying to find out the casting date for my 74B. Does anyone know what B would stand for?

Reading from the lower left and clockwise it reads B 1 3 I am pretty sure the B is not an 8

Thanks

Can't help you on the date but had to read the post as the title implied you might have been starting an engine swap or removing a couple cylinders if you catch my drift.

Sounds like August 1, 1973 (if it's the little "clock" under the distributor).

Thanks.. That would fall nicely into the manufacturing date of 10/73 for my B
