Have spent some time searching the web and can't seem to find any info on factory small block clutch specs. I'm specifically interested in the static clamping force, both base 289 and hipo. It's time to pick a clutch kit for my 67 GT350 and want to stay with a Long style, non-counterweighted pressure plate. Will be street driven and looking for an original "feel" on the pedal. Going with all stock clutch linkage and don't want something so heavy that things start bending. I have a previous post up looking for the specs on an old Hays 10CF plate, circa 1981, which I have and is in almost new condition, but don't know the spec on it. Shelby Parts recommends the McLeod with an advertised static force, of 1800 lbs. Hays has their Street 450 kit, 91-2001 with 2800 lbs, according to their tech guys. Quite a difference for 2 "street" clutches. Would like to have numbers on the factory pieces to compare these to. To be honest, I haven't found any other manufacturers offering the Long style set-up. NAPA, chain store?? Any thoughts, opinions or suggestions are much appreciated. Thanks. Brian
