Thread: what transmission behind your bbc?

Tweet

Thanks for the help guys, just got a th-400 and dropped it off at thr tranny shop for hardened shafts, sprag etc, i can hardly wait to see how much money it is going to cost me , i found a th-400 on a website claiming it will handle 900 horse for $1500????

alot of guys will warranty stock builds but never a performance build 99.9% of the time anyway

i know especially if they know a big block's in front of it

When I had mine rebuilt at the local performance trans/converter place, I was surprised it only set me back about $700... In addition to the shafts and sprag, ask for the waffle-style clutches, they tighten things up quite a bit and should not wear as quick as the conventional clutches (?). Unless you're looking for nice smooth shifts

i like it when it shifts and it tears tendons etc.in your neck, only way to go, if i wanted to shift smooth id buy a Kia, NOT!!!!

I am running a 496 stroker in a 3600 pound car running 10.30's with 1.42 "sixty footers " with a tci built turbo 400. No problems with the trans ever !

^^^ nice! What car is this? Do you have pics?

I have 3 candidates for cars, i have a 80 malibu 2 door, an 85 regal and a 84 monte but is in sad condition, i am building a sleeper car, nothing that looks to fancy, going to run mini tubs with ladder bars/ coilovers on a 9'' nothing too big, i want people say "GOD WHAT WAS THAT?", i am going to cage it, allready have the material just need to do it, get vacation in a couple of weeks so i think i will decide which car i am going to use and get the cage done and start working on the rear end, i do know for now i will definately have traction problems so there is not going to be a huge strain on the drivetrain, until i can tub it, but if i do it right there are people running 8's on 10.5'' tires, allready have the fuel system minus a fuel pump big enough to run this beast car shouldnt weigh more than 3300 but thats just a guess, could be a little more especially if i ran the monte but i have ruled that car out, too much work on that one

All in all it will 95% street driven which might be once every couple weeks if i am lucky, i work about 100 hours a week so not much time

I am just questioning for the point of edicating myself as my engine and car building expereince has been limited to small block and 454 motors etc. 95%/mostly street car, 10.5" tire. Why 632 cid, 340cc runner heads, on a 3300 lb car running 13:1 compression most likely not able to run on pump gas? For mostly street. dont get me wrong, Im sure it will be a wild motor and fun as hell but on a 10.5" tire, and for a car that will be blasting mostly on the street cant you achieve the same performance pretty much with a lot less discplacement, compression and such huge heads? What are the cam specs, and stall speed gonna be? What the cooling system gonna consist of? Just seems like a lotta motor for a primarily street car. Ejumacate me please.

heads are not that big for a 632 and they drive fine on the street.i think the cam is custom
