You Block Casting number 3733949 is a 235 for the 1954-55 cars and trucks. With a date code of F 6 8 that tells me it's a replacement block that was cast June 6th 1958.
CON 2 is the conveyer it was cast in...
Is there a number stamped in the flat machined surface next to the distributor?
The 235 head 3836848 was first used in 1953 and is a desirable head to have.
