Many years ago we had a customer who raced a '69 or '70 GTO Ram Air Stocker
400 manual trans.

It routinely tore up bearings and cranks and we did many of the usual things known to help a Pontiac especially in the bottom end dept.

It also broke driveline parts since the engine made a lot of TQ.

Eventually he put a Turbo-400 in it and I drove it a few times.

I did like that car and it stayed alive a lot better with the automatic trans...

I cannot picture a 389 going over 8000 rpm for many runs back in the era Jack Mullins raced. I saw that car race. The parts availability back then was a long way from what is available today...
