anybody smallblocked a d50? how about turbo'd one?

A few decades ago my boss had a Ford Courier (?) that he had put the drive train out of a 68 Cougar in. Rear end dropped right in but the 302 was a pain. Do you remember the D50 converts? Cool pick up with a canvas top and a pop off hard top.
I remember those...back in the late 80's when I was a kid my cousin was into the minitruckin scene. He did that on a Mazda pickup.
