Ok-6 months ago I had a similar thread and NO ONE responded to it--Whats up with that-Now guy's getting heavy about Alum/Steel flywheels on this thread.There still is no conclusive responses about the alum flywheel. I have a 70 Duster with a 833 and have to change out the clutch this spring and was thinking of going with a alum flywheel ,But no -one would respond!!!!!! My Duster is a STRAIGHT street car NO TRACK time-- SO ALUM OR RE-SURFACE my steel fly wheel--I'm adding a dual disc clutch (McLeod) OH sorry motor is a NON stock 5.7 with a 150 shot of juice at W>O>T Any help guy's I would be very thankful--Steve
