How heavy is your car?What kind of converter?What kind of E.T./HP?I'm making "about" 700 hp,3300 lbs,me included and am using all stock TH400 internals,except for a manual valvebody and good clutches.Stock parts are stronger than you think.Just a thought,though.You know how they say "Pro gears"(ring and pinion) are actually softer than a "street gear" to help absorb shock loads?Whereas a street gear is "hard" so as to hold up on the highway for a long time.Seems like hardened parts to a tranny would be going in the opposite direction. :?: Like I said,just a thought or brain fart,depending on how you look at it ops: But,give us some info on you ride.I might not have the info you're looking for,but there are some really sharp guys on here that will.

i am running a setup like olds48 and have had no problems with the car even launching at 5000 on the brake. all i added was a reverse pattern(which i hate) and a jw bell. goodluck with your car i think you will be fine
