    tubecatgs Finally a 4 speed......

    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!

    I went with a stock acdelco clutch, easy on your left leg and shifting is like butter!

    Centerforce Dual Friction is a good choice.

    Centerforce 10.5 dual friction will do ya fine.

    I have ran or installed pretty much everything,and I don't really have any negatives about any,but the majority of them have been Centerforce,and my own cars have Centerforce.There are a few different levels,and far as grip,pedal pressure,etc. I always get at least one step up from stock,even for a resto or stock car.

    That same clutch disc is available at Summit for $105. That particular part number is for a 26 spline input shaft though.

    Thanks. Forgot about the input shaft I need a 10 spline. I ordered a kit from Summit. Haven't looked yet but any tips on installing the clutch and new throw out bearing? Engine/trans still out of the car.... Never done it before. Thanks all!

    Should be as straightforward as your removal process. Disc goes in one way, its marked. May want to check pilot bushing for wear, if you replace it make sure it fits the shaft and the hole. May want to check flywheel surface, may need to be machined

    Just for reference I installed the RAM a few months ago and has a great feel.. not too much pressure...works great!
