I've got 3000 miles on my rebuilt 406 sb. When I installed the engine, I replaced the clutch with a Centerforce 2. Replaced the throw out and pilot bushing. My question is-when I start the car, it tends to roll forward until it's warmed up. When I push in the clutch, it stops rolling. Let out the clutch, car begins to roll again. We play this game for three or four minutes. Car does not roll far, but am I in for premature wear on any parts? I changed gear oil in the tranny when it was out of the car with the proper wt. Thanks
