Viper T-56 to LS conversion Ok guys,
I have done a few hours of research here and am struggling to find exactly what I need to buy and do. I frequent a few other sites and learning to navigate another one is taking too much time.
Here's where I'm at. I have a Viper T-56 that I bought new in 2004 that was finally on the road all of last year behind the big block in my Chevelle. I used a lakewood scattershield and adapter plate with mechanical linkage. Now the big block is gone and I am installing an L92 and want to run the stock LS bell housing and a hydraulic clutch. Obviously I need a new flywheel, but can I run my existing Centerforce clutch and pressure plate? Can I just switch input shafts or machine mine down? Are there specs for that?
Any help would be greatly appreciated!
Tom

If you're going to run an OEM LS slave, you'll need to swap the viper front plate to an LS F-body front plate because the bolt clocking is different.
Were you using the viper input shaft on the BBC with a mopar pilot bearing or was the input shaft pilot already machined down to the GM size?

You " should" be able to use the aftermarket "RAM Hydraulic release bearing kit 98-02" for this app, but I haven't tested it. It uses flex lines so the clocking shouldn't be critical, assuming the lines are long enough. It costs more, but would probably be cheaper than OEM slave + new front plate.

Learn something new every day I guess. I've only worked on a handful of Viper units in the past 15 years of doing it and they are far and few between. 99% of the stuff I do is GM and a Cobra unit here and there.

You shouldn't need to purchase one. All you need is the measurement to the tip of a LS1 input shaft and where the clutch splines start. I have a local machine shop I use and have the shafts cut down to the proper size and have a case hardend bushing pressed on where it rides in the pilot bearing. It just barely has enough clutch splines left to work on a LSx application. Or atleast the ones I have done do, the later model Viper shaft might be different.

Well, I ended up taking the T56 up to RPM Transmissions since they are semi-local and having them install a new mid plate and LS input shaft. Today I will order the complete hydraulic clutch actuator kit and adapter flywheel (so I can run my old school BBC/SBC centerforce clutch) from Keisler Engineering. I also purchased a used LS bellhousing, cleaned it and powder coated it. Looks like I am well on my way to getting the trans issues sorted out so I can get this L92 swap done. Only about a month left before our first Pro-Touring event! Thanks for the guidance.

Just the midplate and input shaft. Although I really like doing most of my own work, paying a professional to make the swap seemed like the way to go. I'm not sure if the tail shaft housing is different, but I was using this trans before so I know it will work for my application again.
