need help

any chevy v8 (90 degree but not chevy 2.8 v6) tranny if thats a chevy 400. if it is a "bop" 400 then any non chevy (even chevy 2.8 v6) gm tranny.

i want it to stay chevy parts so a chevy 400

i wasnt sure which 400 you had because there was at least 4 different 400 v8s. try a t-5 or a t-56 from a camaro.

how much hp can they handle stock because the motor is going to have flat top forged pistons and all eagle internals

lets say this the t-56 is also in the viper.

T-5 from a camaro is a good start, it's what I used for my swap and so far I like it, but I'm only running a mildly built 305. Additionally the camaro T-5 is only rated to handle 300 ft-lbs of torque in stock configuration. I picked mine up for $300, but recently put another $600 into it to have it rebuilt. Summit Racing sells a version that will handle 400 ft-lbs of torque for I believe $1600. The T-56 (used in 1990s c4 corvettes, and yes Vipers) is also rated for 400 ft-lbs of torque (Viper units I believe were higher torque rating. However may have a different input shaft so I am not sure if one from a viper would be a direct bolt on), and a used unit will set you back the about the same amount of dough as the Summit Racing unit, unless you get a smoking deal.

if you haven't decided on the trans you want you might want to check out the car auction site http://copart.com. I don't know a lot about cars but my boyfriend is really into them and I used copart.com to help him find cars with the parts he needed in the past...including a new transmission. might be worth checking out...

t5 is not the strongest of a transmission go with a t56
