yeah, you'll need a tranny from a 5.0L, or BETTER to handle a 351's torque.el docum said:Hello,
I'm new on this forum and I need help for a friend, he had a 1995 Mustang 3.8 L and he want to replace to engine by a V8 351, he want to know if he need to replace the transmission or just the belhousing, I think he will need the transmission from a 5.0 L but I want to confirm it.
Thank's for your help.
If it's a performance build, you should ditch ANY ideas of using a t-5 and go with a 3650 or t56.
A t-5 from an old 5.0L will go south in no time.
You're going to have to change the rear end, and the front springs & struts, and you'll have to work around the PATS as well . . .
