Re: Anyone swap in an lt1 with the original sm465?
Pretty sure the 6-speeds have a different clutch type than an old 4-speed. I think you can use a Vortec 4.3 or 5.7 Flywheel for a 5-speed with the pressure plate for the late truck and a disc for your original truck. Just be sure that they are the same diameter.
