Title: 5- speed
Post by: Bruce R. on May 04, 2017, 04:32:24 PM

Anybody know a good junkyard source for a 5-speed to stick behind an FE ?

I would imagine a T5 out of a 80's Mustang would work with a Modern Driveline adapter plate as I believe it is the same bolt pattern and input shaft as my Tremec 3550.  I would worry about fragility as I think even the "World Class" was only rated for 325 ft-lbs of torque.  I worry about that in my 3550 as well as it is only 375.

I dont of any that would hold up , they had problems living behind 5.0 s or 4.6 s , a tko 500 or 600 would be best ..Bud

I broke 3rd in a T5 behind a bond stock 86 5.0

No missed shift, no powershift, just normal hard street driving.  If you drive easy a T5 will be fine but I'd go Tremec if you plan any abuse

The only reason I brought up the T5 is that he's looking for a junkyard piece.
