big block vs Tranny

[d10s69c10]

Well i just picked up my 454 today.. came out of a 84 3/4 ton turn key for $500
i think i got a good deal. ill get pictures later

350 staying in it another year im sure (while im building it).

i want a Manual not an automatic just for the sake of keeping it simple.
i plan on turning the BB into a 496 and ball park 500hp/600tq nothing to radical
what tranny can i get that will hold this stocker or built up.
was thinking a 5 or 6 speed out of a comaro ss or a corvette but i could use a few tips if anyone has seen this done or looked into it. running 4.10 rear end at them moment and ill only turn the motor 6k max.

Ideas? facts?

in all reality, "to keep things simple" you'd want a TH400.

[mnunn454]

Agree with Longhorn Man on the simplicity of a TH400.

I don't know of many (make that "any") stock manual tranny's that'll handle 600 lbft of torque.

Aftermarket tranny required, I think. And for those I'll bet you're going to spend more than $2000.

The TH400 in my 454 powered 69 short Fleet works very well (that is until I "borrowed" the engine recently for my 70 Elky).

[thirdstreettito]

TH400 is what I suggest if you are on a budget.

[BentHeadBolt]

I agree with longhorn man too! If the vehicle it is going is already set up with a stick then maybe OK. Putting a stick in a vehicle that was set up as an auto is not what I would consider simple. Nor quick but it can get dirty. Just some mindless thoughts from a 60 year old rodder. Later Specs

well when i said simple i meant i like the closed system and less moving parts to worry about later on. ill roll the th400 thing around but im still bumping the thread cause i would love to see someone else that has done it.

[steelhorse]

Call Kiesler(?) and check on the TKO they have put those behind some pretty stout motors including built Hemis

[Long Roof]

I know of no readily available stock manuals that could handle 600 tq. Sounds like an aftermarket, race ready manual or auto. Even a 400 would have to be built. Richmond maybe?

[Techy]

a Slightly built T56 from a camaro/corvette should be able to handle it.

[sickchevy68cst]

no it wont the only t-56 thatll handle it is a viper specced t-56 cuz it has smaller 1-2-3 gears than the rest.. i just got done doin the 496 route forged internals aluminum top comp cam (LOL)ford lifters(LOL) 850 quickfuel vac sec. msd yea put me back like 7,500 total for the thing

I am going to buck the 400 trend...they tend to lose more HP in the driveline than a 350. There's a guy here that my friend knows who races a 600 hp BB with a built 350 behind it most every week...he's going to build my tranny [he builds trannies for a living].

As far as manuals go you can get a Richmond 5 or 6 speed [good to 600hp right oout fo the box]...might cost a bit, but if you are dead set on manual, these are the ones to look at.

I just got done building a 496 with solid roller lifters, solid cam 652 lift ,edelbrock rectagular alumi heads...I think I am going the Tremec TKO 5-speed.

[68GMC454]

ok i got a 84 454 out of a 3/4.. been told alot of times there isnt a 5 speed that will bolt up to it.. not sure why i gavfe up looking for one years ago.. wanted to get away form the granny tranny i had.. but would rather have a 5 spd, than the turbo 400 that is in my 76....so is there a 5 spd i can go get out of a junkyard that gonna bolt to my 84 454..

[Longhorn Man]

any of them will BOLT up... its making one HOLD up that can be a pain.
