Hey all, being that 80-86 F-trucks never came with a PSD and I like the lack of wires n boxes on my oilburners, what do I need to convert my 84 F-truck from a 351w to a 6.9. Heard a bunch of different things like the crossmembers are different and springs are heavier (makes sense)...also, (not real swift on makes/models/sizes) what mods would be neccessary to run a Ford 9600 (401/6.6) tractor turbo on a 6.9, I can score one pretty cheap is why I ask. Either that, or I could prolly get my old turbo setup off of my old 94 7.3 turbo (don't own anymore, but it's close).
