***REQUIRES UPGRADED VALVE SPRINGS***

Jim designed this cam to work perfectly for big bore 131-135 cubic inch Milwaukee 8 engines. As with all of Jim’s cams, it generates a very flat torque curve across the rev range and makes its peak HP between 5500-6000rpms. If horsepower is what you are after, this is the cam! It pairs perfectly with upgraded cylinder heads and an intake tract size between 64-68mm. It produces a very distinct “choppy” idle and very aggressive rumble while revving the engine! You’ll hurt some feelings with this bad boy! Leave everyone in the dust with this bad boy installed in your engine!
