anybody have info on the NP833

[treveiger]

I have a 1969 c20 with a 307 and a sm465 for a transmission, the tranny is getting old and i was looking at getting better gas mileage as im turing it into my daily driver an later on im going to switch my motor to a 350 an would like to keep the transmission i buy for it or buy both the transmission an motor at the same time. I heard good an bad things about the NP833 an i was wondering does anybody have any information on it, what they were in, what they can withstand, how much power can they handle before breaking, how they cruse down the inerstate, basically any and everything about the transmission would be great. Does anybody have any history with them, is it good or bad an if so why?
Thanks
