Hey bud, you break last time out? I don't think you're going to do much better switching to McLeod or Ram non-adjustable. They're all pretty similar coefficient of friction/static pressure to hold similar power. My Ram Powergrip HD is like a dump truck clutch.

I think if you go adjustable with an aluminum flywheel you at least have a chance to improve your 60 ft too. Coming out at 5 grand will be easier on your trans. You can switch to a Ram adjustable setup pretty cheap, and if its a stock flywheel I would change the flywheel to a billet one anyway. That thing is taking a beating for a 50 year old cast piece, don't want that coming apart even with the scattershield.
