Hi All! I'v been a member since 2009 but not been very active. You know, work and all the stuff that gets in the way of the fun stuff. Now retired . Anyway my name is Dave Raska I live in Radcliffe, Iowa. I live and breath Route 66 and Chevrolet wedge motors. Now for my problem. The clutch in my 63 SS 409/340 is very jumpy. I have tried everything I can think of. Maybe someone out there will have a idea. So far I have changed the clutch and flywheel many times, new trans ( 2:56 low) Different drive shaft, Different rear end 3:71 ratio. Had rear main seal leaking so overhauled the engine, checked motor and trans mounts while motor was out. Also have changed clutch linkage. The clutch will jump when moving from a standing stop, will not jump when leaving from a rolling stop. Also will not jump if I put the E-brake on just a little then move. If anyone has any ideas I'm willing to try it. Thanks Dave
