xcsam 10 Posted March 31, 2013 G'day, I just got myself a Tremec gearbox in good condition that was said to be removed from a Ford. I am aiming to build a 400hp 351 or storker clevo for my XC ute. Previously, I was planning to fit a T5 gearbox from an XF to my ute, but lots of people have advised me against that due to the weaknesses of the T5. Was the first Tremec gearbox the 3550? If so, they are rated at 350 ft/lbs or 474nm for torque, compared with the 265 ft/lbs or 359nm torque of the earliest T5 box. If the box I got is a TKO, it is rated at somewhere between 375 and 400ft/lbs of torque. How do I interpret the torque ratings of the gearboxes. Do you guys reckon that it will be adequate to stand up to the 400 flywheel hp that I am hoping for out of my clevo? Will I need to a) modify my existing single-rail to clevo bellhousing that I was expecting to use, modify the bellhousing that comes with the box, or c) purchase a specific tremec to clevo bellhousing? What are the options for my clutch setup? Thanks guy! Share this post Link to post Share on other sites

xcsam 10 Posted April 2, 2013 Ok, cool. I am picking my gearbox up tomorrow morning and i'll let you know exactly which one it is, but judging by what you guys have said, it's exactly what I need for my clevo. Share this post Link to post Share on other sites

xcsam 10 Posted April 2, 2013 I've been doing a bit of research on the TTC- Tremec website, and it looks much like an earlier Tremec T5, not the TR3650 as seen in the BA Falcon. Share this post Link to post Share on other sites
xcsam 10 Posted April 3, 2013 The number on the gearbox is 13-52-065-922, which means it is a T5. Looking online for those numbers, it appears that it was from a 5.0 V8 Mustang between 83-84. The ratios I found are: Reverse- 2.76 1st- 2.95 2nd- 1.94 3rd- 1.34 4th- 1 5th- 0.63 Torque- 305 ft/lb Share this post Link to post Share on other sites
