I’ve got a 727 with all the normal heavy duty must haves, billet front drum, super sprag, steel front planet, billet servos and heavy struts and pump gears. I’ve got the trans out for a converter check and refresh, and just considering my remaining options for making it even stronger. Who has had a failure with an input shaft/hub, or an output shaft? Both look to be approaching $1000, so trying to decide if one or the other is more of a weak link. Also considering a rear roller kit.

Car is 3600 lbs with driver, leaving off a transbrake, running low 10’s, 60’s high 1.3x, and hopefully a little faster in the future.

Thanks all!
