I am about 2-3 weeks away from getting one and have some questions.

No one that I know of, though I have thought about it. Should be PLENTY strong. The problem is getting it in. If you use one from an f-body, you have the hydraulic slave/clutch to adapt. You also will only be able to use buckets as the shifter location will be too far back for a bench. Finally, you'll have to either use an electric tach or get an adapter. Or you could use the aftermarket t56 which will solve all of those except shifter location but it's around $2000-2500. If you're willing to do some fabbing and adapting and use buckets, it WILL be SWEEEET in every way.

Btw, where is Paradise?

[67Fleetsidedream]

Yeah it will be sweet. I might just be the first person to ever do it. But someone has to have beaten me too it. I wonder what problems that I will run in to? I will be definetly be getting the modified Tremec T-56.
Paradise Texas is north west of Fort Worth.


Any one???

If you get one from an f-body, get one out of a 93-97. The LS1 has a diffent bolt patern and crank position than the standard small block, reqiring a custom bellhousing that I doubt anyone makes. The LT1 t-56 should essentially just bolt up (except for the things mentioned above)

[jmil1974]

Ack is right, the LT1 ones will fit much easier. You should also avoid 93 models if possible. They will work but are a touch weaker and have funky gears. The 94-97 ones would be best. You'll also need a special flywheel (Centerforce makes an adapter) if your engine is the older (85 and back) 2 piece rear main.

Do they make a truck shifter for the T56?

68lss1 has a ls1 and a t56, maby he can help.

[Ackattack]

you could probably use a stock shifter and just make a longer stick for it pretty easily. Or use an aftermarket shifter and put a longer stick on it. The aftermarket shifter would keep the throw down with the longer stick.

[jmil1974]

Ima go with ack again. The stock shifter on the LT1 T56s is long enough on its own to be a truck shifter. I replaced the one in my Z with a B&M Ripper and loved it. I'd go stock first and if that's a no-go, then like ack said, fab a longer handle for a Ripper or a Pro5.0.

My pickup had a three speed on the tree until I lost 2nd gear.
Will I need a high hump for the transmission to fit?


Any Ideas?

Since you can probably pick up a high hump pretty cheap, I'd get one to have on hand and resell it if not needed. My guess is - tall hump, since the 4 speed trucks came with high humps (along with TH400s and 4x4s, if I remember right from other posts).
