The LS9 engine we are running comes with the corvette pilot bearing which has the big clunky bearing. I was told by D&D that I could run a Pilot bearing GM has been running from the mid 50's to present and his spacer and everything would work. I was just hoping someone had maybe done this swap specifically and could let me know. This build is for my brother in-law and I want it to be perfect without having to buy multiple parts just to send it back because it doesn’t work. When we bought the engine it came with the LS9 flywheel and dual disc clutch. I’m hoping I can run the LS9 flywheel, LS9 dual disc clutch set up with the small pilot bearing, the Keisler magnum T56, Keisler hydraulics and the D&D spacer. I was worried at first about the D&D spacer and the hydraulics do to very little adjustment on the hydraulic set up. When I researched it more I found that the spacer goes between the Trans and bell housing and not the engine and Trans. So there should be no effect on the throw of the hydraulics. Please let me know if anyone thinks otherwise.
Thanks Chris
