Help me date this 302

Guy was told it's from an 89 fox. Looks to me to be coded to be 81. But looks to be a roller block....
Thoughts?

8F20

Cast on June 20th, 1988


There should also be a partial VIN up on the rear China rail area


However, a Mustang 302 block will be cast E7tE. That appears to be an e1te block, which I believe is a truck 302 (not positive)

I'll have to look at my block I have on a stand. Supposedly it came out of a 1989 or 1990 Mustang.

I also just had my trans out and didn't notice any numbers, but I wasn't looking either.
 
Blocks are blocks for the most part. Difference would be the internal parts, mostly pistons and cams.
Truck 5.0 engines had the 302 firing order and lower compression pistons.
any other differences or if I'm wrong will be noted by experienced members.

It is a 1 but it is supposed to be a 7. Whom ever was in charge of setting up the engineering number on the blocks that day at the foundy picked a 1 instead of a 7. No an uncommon mistake.
