Contact Glen Buzek bout upgrading your T-5 internals, or see how much fun MS is having with his Tremec installation. YMMV.

Tubo

Can I cut 3/4" off?

Is there a spacer plate made?  Are the 93-95 T5's stronger/greater power rating?

What about if I go with a Tremec, do I have further modding? 

Also, what if I go with a 99/00 trans, is that possible?  One from a Camaro or dodge?

Thanks guys, much obliged

X2 on sticking with the original T-5.  A "world class" should work well and if you have access to a cheap stock transmission, throw it in and have a stout one built with ratios that will take advantage of your engine and your rear gears.  If everything else works like clutch, shifter postion, etc., I wouldn't change to the longer input shaft version or a TKO.   I went through the TKO mod on my car and to get it at the correct driveline angle requires a lot of work.

Steve I've been looking at the TKO 600 to go behind a warmed up 390 in a '67coupe any pointers at all would be appreciated from what I gather the T-5 won't handle the torque of a FE, this is a scratch build and am currently replacing floorpans so tunnel mods would be easy at this point. Oh yeah any one have a source  for inexpensive TKO's. Thanks

Commish, what driveline angles did you wind up with?

Is that to mean the tail is pointing down 6 degrees as referenced from the frame rail?

If you do go with a TKO order it with the short input shaft - most good suppliers will quote this option.  You will probably have to switch to a different disk to match the splines but everything else should be a good fit.  I swapped a large-spline close ratio toploader out for a TKO in my Cobra and the clutch disk was the only thing I had to change.  I was running a Lakewood bellhousing but an original bell should be OK.

When we did the tremec 3550 swap on 65 2+2 many years ago, had to notch the tunnel opening on the right side and modify the crap out of the conversion crossmember to fit. We had to play with driveline angles, but once you get the two to cancel out,  you are fine. 3 degrees is optimal, but sometimes you have to go to 6 or 7. Worked like a champ. Put 1 in a 68 cougar no problems at all. If you want a t5 check out g force transmissions in cleona pa, near me. They have many optionsbon bulletproof t5's( make em for NASCAR even).

Thats good news as I've got enough welding to do without making more on the old horse.

I am also using a TCP rack, only mod was to clearance one of the header tubes on the drivers side to clear the tie rod.
