Well John, I’ll have to dig it out of my old manuals but I believe there were two different transmission codes for it meaning there were two different models. Discredit me? Like I have any credit to begin with! Give me a few and I will find it for you. Oh, about the smallblock C6, we’re talking 302.

For what it's worth, my 76 F100,
302 auto G code has a C4.

 

That is exactly what I expected to hear, not about a C5 or some other thing in a truck.

Well the C5 answer was probably right.
The C5 is just a heavier version of the C4 that is used in Trucks.
if you look at the pan and the dipstick screws into it,
than it is the C5.
Also the torque converter from a C4 will not interchange
with the C5. ( C5 uses a larger & different bolt pattern ).
Also the C5 uses more cluthes in the drums.

 

back to the small vs. large thingie. Can't describe large, but I sure know what small looks like.

 

I don't believe that Ford pickups of the 70's era had C6/small block. Vans and pickups of the 80's vintage, did. Most Vans had smallblock engines in the 80s 300/302/351W... the others would have been diesel and 460. Vans needed a heavier tranny for the hauling they were susceptible to. Smallblock C6's were also mated to 351C in things like Mustangs, Torinos in the 70's. I have a smallblock C6 on my garage floor that was bolted to my 302. A C5 is an aluminum cased C4lite. If it was stock from the factory, I say its a C4 behind the 302 in 76.
