I am converting my car over to a 4 speed. I need a new clutch kit and need a little guidance for what to buy. Are the usual parts store clutch kits good for a mild engine in a street car or should I call summit racing and buy a big name brand for three times the money. My car is a 67 Dart with a 340 ( less than 350 hp ) with 3.91 gears. This is a street car that won't be run hard much other than just an occasional burst to clean out the exhaust.
