I bought a power-lok for my street/strip (mostly strip)71 Duster today, it’s brand new with new Tiimken side bearings. Got it for $325 so I think I got a good deal. I’m curious as to how much horsepower and torque it will take, as it’s going behind a 410 stoker that should make 475+ hp and 500+ ft lbs of torque and will have a 4.30 gear. I previously ran a factory cone type suregrip in my D100 street strip toy and it held up decent but I’ve always heard the clutch type is preferable. What do the masses think, will it hold up good?
