I was given a 302 H.O. (so the guy says)out of a 1991 Ford F-150.

It was a long block only.

I tore it down and have only found a few numbers on the block:

3m17
FISE 88
54

and one of the crank bearings has a readable number:

D.A.B.
1293E
C50E-6A338-A-B

Can you guys tell me what engine I have from that????
It has a roller cam in it also.
