    400

    do you think a 400 with steel drum 34 element sprag with hardened input and output with transbrake would hold up.or should i also add new herdened gears if available.. thanks for the help

    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

    Reverse patterns DO suck IMO.The vbody is okay,but can't find a shifter I like.

    Air shifters seem like they would take the fun out of driving.......but WINNING is fun,too
