302 date code?

Hey guys,

I am going to be building a 302 (just a bit over stock) for a future project. I have a 72 block and heads. D2OE casting number. The rebuild kit I want to buy (northern auto parts) needs to know if it was before may 1st of 72 or after.

What is the difference and how do I tell the day of this motor?

Mike

There were two deck heights in the '70s.

8.206 & 8.229

I'm guessing that's what they are trying to determine....which one you have.

The best way is to measure, but that's not always possible or practical.

Look on a ledge above where the starter mounts. There should be a casting # with a date code. Date code will look something like "2D12".

Also look for a date code on a small flat machined surface just in front of the #5 cylinder on the front of the block.

That will be the original build date of the engine.

Most books refer to '73-'76 as the years with the higher deck.

OK here is what it says on the starter flange spot

D2OE-6015-AB
3B8

The second set of numbers (6015) that could be an "o" instead of a zero...

Hope you guys can help

Well, I don't have a listing for a D20E under 302's, but that doesn't mean much because Ford cast a lot of blocks

D - decade - 1970
2 - year - 1972
0 - Fairlane/Torino car line
E - Engine series

6015 - base part number for engine block casting
AB - Engineering chance level or similar

3B8 - February 8, 1973

3 - 1973
B - February
8 - 8th day

Thats the way I read it, anyway.

Thanks ckelly!

So this was cast in 73????

It also has a large "0" and a "2" kind of off to the side of the casting numbers... Don't know what they mean...

Anyway, Is this block any good for building? I plan on running flat top pistons with the original heads which are also "1972" castings (they have been with the motor since new)...

Thanks everyone!

Thanks Kermit, but those articles were based on a 85 HO roller block (this is a bit earlier)...I don't plan on 400 horse...just a touch above stock...I just wanted to make sure that this wasn't "a bad year" for blocks/castings...

Also as for the casting pad in front of the 5th cylinder, it is completely blank. Like nothing has ever been there or stamped there...nothing. Is that normal?

Later,

Could this be anything else? It was in the falcon ranchero basket case...I guess I just assumed that it was a 302. (It was just the long block and no tin when I got it) How do I know if it is a 351W? The bores are 4" (I haven't measured stroke and everything is apart now ready for the machine shop)

Thanks again!
