TH400 recomendations
Kind of a Generic question: For a street car big block motor car/occasional strip: 500 hp/Ft lbs in a heavy car like a chevelle what upgrades would be suggested when you go to your local hi perf trans shop?
I have head people say anything under 600hp in a street car occasional strip a stock Th400 will do just fine. I have blown quite a few Th400s in an old stock 77 GMC 1/2 ton 454 pickup that I beat the hell out of as a kid so the stock thing doesnt seem appropriate with me.
Im no trans expert and when walking into a shop to discuss rebuilding, it would be nice to know what it is I should want, and know what Im speaking of a little. Just trying to educate myself basically.
thanks in advance for the replies gentlemen.

Well I hope you don't drive like you did when you was a kid. When I was a kid, I didn't know that going in reverse and throwing it into drive doing "J" burnouts would kill my transmission.
A good solid thourough rebuild (new steels too) with replaced wavy plates and a good shift kit set at HD instead of "race" will handle some good power for a street car. To me for a street car, a too solid of a shift just tears stuff up. If you abuse the tranny, I'd dought a high price built one would hold up for a long time.
Like Denny said, go talk to a few shops. I wouldn't act dumb though. Tell them what you have and what you need from them. They should want your business and you as a future costomer. They should give you all the answers you need. If you don't get a good feeling from visiting and viewing their work conditions, just go find another one.
Well I've sure gotten old too so don't worry about it! I've had two bypass surgeries, new knees, fought prostate, cancer and diabetes. I'm half blind, can't hear anything quieter than a jet engine,...
