I pulled the 302 out of my '73 F100 to rebuild it. Dad was pretty sure the engine had been changed before.
Block number as best I can see:
D20E-6015-AB
Number beneath that is:
3F26

So, that's from a '72 Torino?

The heads are:
D3VE AA

Unless the stock really sucks I think I just want to go back with it for now. The truck hasn't been driven in about 12 years now.
What do I have and what's the recommendations?

 

Well for practical purposes - unless you're worried about numbers matching - it doesn't really matter. All 302 engines of that vintage were pretty much the same.

If the engine's apart, go ahead and get a new cam/lifters/timing set.

Stock SBF heads are pretty much junk, although the GT40s flow a little better than what you've got and should keep the compression pretty much the same. Plus they've already got hardened valve seats (required for unleaded gas).

An aftermarket intake and headers will help a ton, too.

 

The heads are:
D3VE AA

That part number corresponds to 429/460 heads.

 

I'm gonna just scrap the block. It's already .030 over and the machinist wants to take it .060 over. Why not .040 I don't know.
I'm going to pick up another block next week out of a mid to late 80's truck.

 

How about D3UE AA? I went and looked again.

 

D3OE, maybe?

If you're getting a newer block be sure to get one that's roller cam ready - '87 and up IIRC.

 

Picked up a block from a guy. He said it was a 302. Brought it home and found the numbers on the block tonight.
E0AE 03C That cold be a D3C

1980 Galaxie? 302 or 351C?

 

E0 is 1980.
A is "full size/Galaxy", which is impossible as there was never a "Galaxy", and there was no "Galaxie" in 1980. So it came out of "full size", whatever that was in 1980. Or not--the casting number indicates the originally intended use, not always what model it came in.

It can't be a 351C as the last year for that engine was 1974.

Measure the bore. 4" is standard for the 302.

Measure the deck height. 8.206 = 302. 9.503 = 351W. With that big a difference, you only need to be close to see which it is.

 

D3UE AA is a valid (casting) number for small block heads. They were originally designed for 1973 Econoline vans so not surprisingly also used in light trucks. They are said to have 63 cc chambers.

E0AE cylinder block is a 302.
