FE Cylinder Heads & Blocks

[devbravo]

I've located 2 FE engines.
The 1st one has valve covers with "THUNDERBIRD"
embossed on them.
The casting number on the heads is: C4AE 0060
Casting number on block 04A DIF

The 2nd engine.
Head: C8AE-H

Casting # on block 59 352
Also 25A DIF

I believe these are both 390's

Would anyone happen to know of a definitive way of determining
the displacement thru the casting numbers?

Thanks

Check the right side of the block toward the front for a different casting no., something like C6ME.

The only definitive way is too pull the head!

I can't tell you what blocks you have without a different casting number. There should be more numbers on the blocks. The numbers should be similar to the head casting numbers. Example: C8AE-A is a 68-76 390 block.

As for the heads:
C4AE = 64-65 352,390
C8AE-H = 68 std. 390 w/AIR

I got that info from "How to Rebuild Your Big-Block Ford" by Steve Christ.

The one with the thunderbird valve covers might be an early block if it has 2 bolt motor mounts vs the later four bolt if original. Check for the date code on the blocks. It's below the oil filter adapter mounting pad and is a number/letter/number(s) sequence. As mentioned look for the casting numbers on the blocks. Fords early blocks (60-64) were pretty good for casting numbers. They did not repeat on different blocks like some of the later numbers.
