D&D T56 mated to a LSX Here one. So I have a D&D Viper T56, the one thats modified to mate up to a GEN I engine. I now want to install it behind an LQ4. Will a LS series T56 bellhousing bolt to my tranny and work? Mcleod makes a new adaptor flywheel for doing this, but I have the parts and am wondering if I can make it work.

Call D&D, they'd know.
Edit: I'm suspecting it'll bolt up but you may need an extended pilot bearing like as if you were running an older style trans. LS bellhousing is only off by a bolt.

I did call, they really seemed to steer away from answering it. But they did point me to the $450 Quicktime bellhousing though.
Edit: The extended bushing is no problem Mcleod and GM both make one.

The bolt pattern is the same just one less bolt hole than the LSx style. The input shaft is a different length i believe and the LSx style usues a hydralic internal slave cylinder as opposed to an external. I forget what else. I'm running an D&D LSx Viper T56 and they are NICE! Good luck man!

I have an internal slave cylinder, and one extra bolt hole (all of yours will line up the the LSx block - I was going to use my sbc TH400 behind my LSx before). I think your input shaft is also shorter than mine. Both of our transmissions have a different gear ratio than the standard T56 if you didnt know that. Rather than having the .70 and .50 5th and 6th gears we have .80 and .66 or something like that.

Here's what I'm faced with:
Get a GM 621 Bellhousing $200.00
Mcleod adaptor flywheel $400.00
Adaptor pilot bushing $40.00
I can reuse my Centerforce DF clutch and factory z-bar set-up.
But if I can use a Camaro LS bellhousing:
Used bellhousing $??
Used flywheel $??
Dont know if I can re-use my clutch on any LS series flywheels?
Convert the car to hydraulic clutch $400.
Did I mention this is so much fun?

Yeah, I dont mind converting to hydraulic set-up. I think either which way, I'm not going to get out of this inexpensively. I was just hoping I could source some used parts, verses buying all new stuff.

I say sell your setup over on www.pro-touring.com. You will get a pretty penny for it for someone to mate behind a big block. Then just buy a new LSX viper tranny rather than adapting adapting adapting.

I would steer away from a hydraulic setup if at all possible. More headaches than they are worth, and they require routine maintenance in a performance application (fluid needs to be changed often) and bleeding them is a pain in the ***. Not to mention you sacrifice a ton of "feel" going from a manual or cable linkage to a hydraulic, there's just no comparison.

Actually i had forgotten, scratch that idea! Haha. The LT1 style hydraulics are bad. The external slave cannot be bled which is a problem i face with my LT1. The LS1 style hydraulics are not. If you do have a slave fail yes you have to remove the transmission but thats not too often if happens if you use a new slave and new fluid. they are NOT hard to get to when swapped into a 1st gen at all. a 4th gen yes but 1st gens are extremely easy to work on anything.
