Your current intake will hold the HP back from what it could be. You could get 50 HP with a hotter cam, but it would be Worthless with your stock vert. You would have no power below 4000 RPM.


You cant go much bigger on the cam without changing the vert.

Define your ability to spin? Can you break them loose @ 40 MPH?

Or just break them loose from a near stop and then spin them at will. Once they are broke loose you don't need much power to spin them off the line.

Breaking them loose at a rolling MPH is different.
