Folks, need to pick some brains about an idea that I got earlier today.
I have a 1993 Ford f250 with the 351w and a ZF-S5 M/T paired with a 4.10 rar.
Im going to be swapping the heads out for GT40 heads, along with the intake and a new exhaust. Depending on motor health I may add a supercharger.
I had the brilliant (or dumb) idea of taking the 1995 Ford SVT Lightning motor (also a 351w, but it produced 240hp and 340ftlp or torque) and rebuilding that and swapping it. Given it would have the GT40 heads and roller cams.
But my question lies in this: lets say I rebuild it to give a touch more power AND supercharge it. The small block tranny is rated to hold 420 ft-lbs of torque with a ratio of 5.2:1 (1st) and 0.76:1 (5th). Im worried that the transmission can’t hold this if I overdo it. Ive heard (with no confirmation) that the big block Zf-s5 could hold 470ft-lbs of torque. That may be for the 7.3psd (or idi year depending)
Can the bell housing be swapped to mate the two? Or can I switch the guts over? Or???
Also: transfer case for 4x4 (already have on the truck stock), i have no idea what I may need if I swap transmissions, or if the t-case is different from the big block motors (460 and 7.3).
Would I need to rob a 460 of its tranny and t-case to make this work?
