Anyone have any idea what would be involved in making an LS1 clutch/flywheel transmission work on an LT1 engine? I think if there wouldn't be too much custom fabrication, it would be a worthwhile mod. The LT1 Clutch/flywheel is ridiculously overpriced in my opinion, as well as being odd in the case of a pull type. You can't turn the flywheel, which cost an arm and a leg themselves. I think a couple bolts from the transmission to bellhousing are the only problems, and the input shaft is a bit long or short, I can't remember. What about the LS1 clutch and flywheel? Any ideas?

 

LS1 input shaft is 27 splines and LT1 input shaft is 30 splines..or something. They are different, so if you change that, you would have to change your transmission as well.
