So i am swapping a LY6 in to my YJ wrangler and i am running a NV4500

I have a clutch and flywheel from a LT1 that was in my jeep. I assume the flywheel wont fit the LY6 motor

But if i get a new flywheel for the LY6 will the cltuch and pressure plate work on the new flywheel its a 10.5 inch cltuch and the bolt holes on the pressure plate measure about 11 5/8 where they mount to the flywheel

I plan on running the Mast cam 505hp, i wonder if i need a stronger clutch, the one i have is just a LUK basic clutch

An upgraded clutch for a 2500 Chevy with the nv4500 should work, as long as you have a Chevy trans. I believe the dodge transmissions use a different input spline count and different pressure plate bolt pattern. Also depends on if you have the earlier trans with the lower creeper gear...

Post up more about Your transmission.

I have a 90s dodge nv4500 hybrid. meaning it has a dodge case with chevy input shaft, so its still 10 spline 1 1/8 DIA shaft that sticks out 6.5" and i have a chevy bell housing.

Does anyone know if the LT1 flywheel will fit the LS1 or not?
