***REQUIRES UPGRADED VALVE SPRINGS***

Jim designed this cam to work perfectly for big bore 131-135 cubic inch Milwaukee 8 engines. If BIG horsepower is what you are after, this is the cam! It pairs perfectly with upgraded cylinder heads and an intake tract size between 64-70mm. Peak horsepower & torque will shift around 500 rpms closer to redline as compared to the M837B cam. It produces a very distinct “choppy” idle and very aggressive rumble while revving the engine! You’ll hurt some feelings with this bad boy! For those seeking maximum power!
