kdavies3 K you can make anything fit if you want. If have been with both a 5 and 6 spd trans for racing. I also have a t-56 sittting in the garage. My ERA has a solid cross member, going from front to back under the car. I had my frame changed to fit both transmissions. Heres the thing
What is the gearing in the rearend of the car?
I run 3.31's and have found that 1st gear is a waste with both trannies.
One trans has a 3.00 ratio and the other is a 3.25. I never use them, even racing. You go about 30 ft and have to shift if not smoking the tires, them less.
A stock T-56 is good for about 600/600 torque and HP if blueprints with better internal parts. Better cones or syncros, new stronger main shaft, better shifting forks, tighter clearances. Have seen them break in GTO's. Skip shift is anything, unless racing in a small tight track, only going to use gears 2,3,4 and maybe 5 on a long straight. ^th is for cruising but also has a down side, (LUGGING) the motor and drivetrain. If you have a torque motor with a small camshaft, you can cruise at 70 mph doing 1,400 rpms. If you have a nasty camshaft and a motor that idle at 900 rpms and rocks the, the vibration and lugging will shake the car and bang the drive train.
Have you looked into a super street Richmond trans??
Bolts into you car, shifter 1" back from spot now. Will take 600/600 continueous power , not peak power. 2.85 firsty gear to move you and .87 for overdrive. New motor I am building is getting this setup with a rearend change to a 3.08 from 3.31.
Alot has been done to the TKO 600 trans to fix the problem they used to have
Having multi points for the shifter is the best in a cobra. Over time and abuse,IMO I just don't see this trans not having shifting problems. Same goes for the T-56 and I rebuild them at a dealership for GM. Rick L.
