I have a 22' Commander with a BBC and a Dominator pump. The motor has had a little work done to it. The displacement has been increased to a 468, Keith Black pistons, mild cam, Weiand Manifold, and a Holley 750 carburetor. The pump was rebuilt about two years ago. The only add ons that has are a plastic wedge, Hi Tech Performance straight snoot, and place diverter. I'm looking for some ideas of how I can gain some more mph. I'm not ready to spend the money on a blower quite yet. Any feedback would be great.
