Mazda or ZF?
If its a ZF, there will be a data label on the side that has the model number, and it will also say its made by ZF. However it is probably not a ZF- I don't think Ford offered it in half tons. I believe that they did make a ZF to fit smallblocks, because Ford offered a "heavy Duty" trans option in the F-250- at least they did in 1988, and the base engine in a 250 in 1988 was a 351w.

Mazda or ZF?
The ZF was in all F-250s with a 300-6, 351W, 460 and diesel. The Light duty F-250s had the 302 and Mazda tranny. The only thing I dont like about small block ZFs is the internal Slave cylinder. I have heard that Ford did have an external slave ZF for small blocks but wasnt around long.
