The T5 (251 V8) is an ideal gearbox for your Cobra up to 300 ftlb torque
-- more than that its the TKO 500 and TKO 600 =600ftlb torque etc(all 5 speed) after that its the T56 Magnum (6 speed) 700 ftlb torque---
---More ? go back to auto
The T5 is used in a lot of different cars --4 cylinder, 6 cylinder and 8 cylinder, GMs, Holdens, Jeeps etc and Fords
GMs have different input and output shafts (GM 10spline Input and GM27 output)
Ford is Ford 10 spline input and 28 spline output
The "AU" V8 T5 output shaft and extension housing incl shifter position is too long
contemplating using an XR6 T5 and swapping the bell for a V8 ? --the input shaft will be wrong length and some are 23 spline input
So! if you are outsourcing a T5 pls consider the above -- we can mix n match in a rebuild if necessary as we have the technology (ie.suddenly it won't be cheap gearbox anymore)
In a Cobra --first choice is a
MUSTANG V8 T5 (pref Type 251)
