I think you'd get better views and an answer if the mods would move this thread from the build/project section to the general section

I can't answer your question definitively. Is it a 3/4 ton? I would think a 3/4 tone 2WD would have a TH400 with either a small or big block. Someone should know for sure.

There has to be some differences between small and big block trucks like fuel lines, mounts, hangers etc...
