My truck: 1965 ford f100. Recently purchased from private seller. Was told it has 302. Unable to verify. Unable to find cast mark. Read online to count valve cover bolts as a 302 has 6. My covers only have 5 bolts. What's going on? Was i mislead by seller about engine?

 

FE engine

 

I finally found the Cast Mark and tried to decode it, but am lost!
CODE:
D20E 6015 AB

So, my question is, is it a 302?
Thank you

 

I said the engine is a FE 331 (352) 390 427 428 etc:
the 302 is a Windsor block 260 289 302 351...

they are not interchangeable... the FE has a Round bell housing... with a C4, C6 automatic or a manual transmission. 3 or 4 speed
So you have a Big Block Ford
Is it a 4bbl or 2bbl?
BTW very hard to tell which CI you have, Ford did not stamp them in fact most of the FE blocks have a 352 stamping
Now that tag is unknown to me.
first it's a industrial engine tag.. the F100 should have a 17 digit number.
Industrial engines I think are for the heavy duty truck line which started around 1958.. and I have no knowledge regarding them
when you buy a used car or truck with an FE block, you can not tell from looking at the block which CID you have.
not with standing someone boring and stroking their engine.
