1972 Buick 350 4 barrel in the machine shop for a mild build and hope to end up between 275 and 300HP when done. Car was originally a 3 on the tree manual car with the 175 HP motor. it now has a Muncie M20 (not a fine spline) The clutch that was in it measured about 10 3/8 inches. It seems all the clutch kits I see measure 10.5 or 11 inches. Its not a high performance car, I might maybe spin the tires once in a while but mainly cruise nights and getting ice cream with the kids. Ebay has clutch kits from $75 to the sky is the limit. Can I find a good moderately priced kit for $100-$150 that will meet my needs and should it be a 10.5, 10 3/8 or 11 inches etc. Any links or exact model numbers would be greatly appreciated. Thanks a bunch as always!
