The Stovebolt Site Forums The Shop Area Engine Shop Need engine and tranny match up

i beleive i am going to build a 383 stroker for a 1958 apache 1/2 ton chevy pickup. I want am gonna make the truck pro street but streetable. The complete engine is gonna be puttin out somewhere between 600 and 850 horsepower. ANd it'll have a chevy 12 bolt posi 3:73 rear end. It turn i want a 5 speed transmission to accompany it but i don't know much about transmissions and i dont' know what would match up properly with my setup.
Thank you very much for any help.

The T10 (?) 5-speed conversion is the way to go, but you will have to get one of the units designed specifically for Camaros and Mustangs, as they can handle the torque.

I'd think you'd wanna search the web for tranny rebuilders who specialize in beefy versions of it. They're out there, for $$$.

800 HP? Quite a motor....

Cheers!

It is the T-5 tranny T-10 is the venerable good old 4-speed.
I would not truyst a little aluminum T-5 behind anything over 500 hp.

I'm still a bit confused as to what would be the best setup and why? If anyone has any detailed info about the t-10 and the t-5 it would be much appreciated. I am trying to plan my actions before construction begins so that i don't have any mid build problems. The engine is gonna be mighty hefty, being powered with a blower and all, i need a tranny that won't break down when the going gets tough. Thanks again for anyone with the time to help...

OK, T5. Thanks! Hard to remember it all when you have CRAFT.

I did some digging on the net about T5s for lower HP trucks. T5s were built for a lot of applications. Many were low HP, and so smaller gears are used inside. Some, like Camaro, etc, were high HP.

If you're gonna run a blower, etc you might want to consider a Richmond Gear 5 or 6 speed. They're built for serious HP and abuse.

There are also some aftermarket folks advertising rebuilt-to HD-specs T5s. Start googling, do your homework.

Cheers!

I would not put a T5 behind anything over 350hp. I owned a 1983 Z28 with the T5. It came from the factory with 195hp. I swapped the engine for a 375hp 350 and could never get the transmission to shift well under hard accerleration. If you plan on just putting around, it would work nice, but since you have 800hp, I know that you will operate at WOT a few times.

Guys, come on, 800 hp isnt that much. If youre going ProStreet tho, I'd suggest trying to find a professional tranny building company that will put a really good warranty on their tranny's. For the drag racing part, automatics are amazing, because they are extremely consistent, plus you get overdrive for cruising with some.

I just had a thought, Hot Rods & Custom Stuff had a TH400 with a Gear Vendors overdrive unit bolted on the back of it. The engine for hooked on was a 502 hp 502 big block and apparently the tranny could take its abuse. With that tranny/gear vendors OD you can basically have a 6 speed automatic tranny.

But if you want manual, you could try and find a newer vette (C4 style maybe) that has the 6 speed manual thats connected directly to the engine (the newer ones are on the rear end).
