And yet another option is to run a 2004R from Extreme Automatics with a lock up converter. I did have to cut the center loop out of my torsion bar cross member and reinforce it. Their Stage 3 trans will hold up to 1000 hp/850 ft lbs of torque. Uses a Reid bell housing to bolt up to small block, big block and Gen 3 Hemi's.

The gear ratio's are perfect with a 2.76 first and a .66 overdrive. With the lock-up on a 3800 rpm stall converter, its like having a 5th gear. Best functioning transmission I've ever driven. One wire for lock-up.

I painted mine black, and have never been asked if its a GM trans, Shhh.
