i have run 10" tci which worked ok in street car
but soon as i put it on the strip, it got fatality wounded,
then got a ger 10" which worked real well for me ,it was a 3500,
then i really moved up to a fairbanks 10" 3500, worked alright

with 410 gear, and a stock converter, and a purple shaft
282 cam , he 60ft a 1.69 at monster mopar ran 13,50
stock converter so much for high dollar converts sometimes,
