I ha e a 95 short bed 5 speed 302 that I am turning into a 351 turbo 6 speed found a rust free parts truck with a 351 and I bought an On3 turbo kit for 351 mustang cheap and a 6 speed out of an 03 cobra anyone tried or done this with an on3 kit if this is posted in wrong place let me know where to put it

 

I don't think the transmission is going to bolt up to a 351 - if it came out of a Mustang with a 4.6 it will have a different bellhousing pattern. The 351 uses the Windsor pattern and the 4.6 uses the modular pattern.

 

Has this project gotten off the ground? D&D offers solutions to mate a T56 to a sbf trans pattern.
