I say go for a Muncie and a conservative gear and let that Pontiac torque do the work or...... Tremek TKO or maybe a Doug Nash.

Thanks for the information.

Another option is a RS500 from Keisler. The complete kit cost $2800. It has a 3.37 first gear so I can run a 3.08 rear end that will have the "off the line" performance of a 4.11 with a .68 final gear ratio.

I'm leaning that way, but if I could get better performance and save money with a T56, I would like to know.

That is a cheaper option. Right now I have a M-20 with a 10 bolt 3.55 rear end powered by a 455 bored 30.over. I'm wanting to change to a 12 bolt 3.08.

T-56 wieghs about 100 lbs more than a Muncie or Tremec.

I never understood the need for 2 overdrives myself.

my 69 has a T-56 attached to a '74 455 out of a trans am. runs great, very high torque, but I cant get the speedometer to work. . .

seriously?

It's all about dropping the RPMs a highway cruising speed, improving MPG and allowing more powerful cars to be produced in an era of mandated MPG goals.

I have a friend that owns a LS1 camaro that gives him 5000 RWHP, and he gets close to 30MPG on the highway
