Henry thats some good rev's out of a 400 poncho!

I also had a M20 behind the 455 I had in my 72 Gto, had a 850 holley, single plane, 10.5:1, ported heads,.540/230 cam with 373 gears and 10" M&H's. Use to launch at about 5600rpms and the car was a weekday driver&weekend racer and I never had a problem with the trans in the 3 years I owned that car.

plus ya just gotta love the whine of a M20 in first gear
