SBC 383 Stroker 420hp need tranny?? T56??

I have SBC 383 making 420hp and need to find a trany to match. I was think the 6speed T56 but i cant find one around here (Detroit, Mich) for around 1200. What other manual tranys could i get? Will the 5 speed hold up?? or will have to get a Th350 or 400 ???

Any help plz??

I can't say I know that much about this topic, but I would think that your peak torque number would be more important for matching a transmission.

Also, there are several variants of the T56 that have different torque ratings.

From the web...

A T5 is rated at 300 ft-lbs
I believe stock T56s are rated around 450ft-lbs
Viper and aftermarket-beefed T56s can go up to 550.

I know that the t5 is not that strong. GM never offered it behind a 350 F Body. I put one in my s-10 with tbi 350 and it lasted for a while, untill I put sticky tires under it. I have seen places that ,with a core, offer a beefed up unit, but I don't know torque ratings. And that is your prime concern, torque not ponies. A t56 would do you great, as would an old 4 speed but they are not cheep either and your gas milage would suffer. If your woried about that. Poor milage is part of hot rodding.

i used a 5spd / 350 in a 80's camaro. it broke twice. it was a nice performer style(cam,intake) 350 and 3.42 gears. awesome street acceleration with the 5 spd. like a fast 5.0 mustang.

if i had the option to use the combo again in a S10, i wouldnt. it costs too much to fix the trans. you can baby it around fine durring break in. you get hornery with the clutch once, its over.

probably the tremec tko is the tuff one for 4k

I would go with a tremec tko. They are rated at 500 ft/lbs and up depending on the model plus they are lighter than the t56.

The Tremec TKO is a great option. There are two varieties. The TKO 500 is rated for 500 ft*lbs of torque and the TKO 600 is rated for 600 ft*lbs of torque.

The TKO 500 has a 3.27 first gear, while the TKO 600 has a 2.87 first gear. I went with the TKO 600 due to my 3.73's in the back... You can also get the TKO 600 in a RR version - which instead of the 0.64:1 5th gear (overdrive) it has a .82:1 5th gear.

have you considered the NV3500(not sure which chevys had this) and NV4500 (chevy trucks 89-mid 90s) transmissions you can find manual transmissions rather cheaply here http://www.car-part.com/ but the 3500s clutch fork is on the oppisite side not sure about the 4500 so a hydraulic clutch ot fabrication would be needed
