TB Race Cam Kit for Big Valve Heads

I added this to my Pitster Pro 140 hoping it would add some to the top end power. I found the 140 is a torque monster down low but it didn't pull as hard up top as I would have liked. I did find this cam adds some power in the mid to upper so I was pleased with results for the price. The engine now pulls all the way too the top without a noticeable flattening of the power.
