I have a 700R4 in my tempest. 389 Tri-power 282/292 camshaft. The transmission was built by Gearstar out of Akron Ohio. They put all of the heavy duty guts in it. At the strip I have more torque than traction in 1st. So I must baby the gas to launch. Great street manners, and I am turning 2000 RPM at 70 MPH. I did put a manual switch in it to keep the torque converter lock-up from hunting back and forth when climbing hills.
