Can you help decode these numbers?

Engine cast # 3738307 F205A CON 8 B48

My interpretation is 235 engine Flint plant, Feb 5 car application. The B48 is Feb ???? 1958?

The Head cast # 3836848 CON 9 E93 = 235 head from 1955-1962/ May of 1959?

Help me out here guys and Thank You

Jerry

Jerry,

Here are my guesses (use the link at the bottom to find locations of date casting codes).

3738307 = 235 1958-1960 block
B48 - depends where you found this - it might be a date casting code (Feb 4 1958)

F205A
F = Flint, Mi
20 = 20th
5 = May
A = 235 engine from regular transmission car

3836848 = 56-63 235 head
E93 = ? May 9th 1963? (if this is the date casting code)

The locations of the head and block date-casting codes are shown on this page.

If it is a car engine, all car engines from 1956 onwards had hydraulic lifters.

Thanks T C, I agree the block is a 1958 235.
I AM a little more puzzled by the Head #'S. The 3836848 is visible outside the tappet cover driver side of engine. I find the CON 9 E93 on the top of the head, under the valve cover, between the 4th and 5th cylinders' valves

You found the E93 in the correct location for a head date casting code.

It might well be a 1963 replacement head.
