Although it's hard to tell from the pics, it looks like your loader has too much bite (below keel) and may be overloading your intake. From the sound of your build I would guess your HP may be 500 or so. The Procomp heads are, at best, equivalent to D0VE heads, and throwing a TR at them won't make them flow better even with a stout cam. You are at the point many of us are at at one time or another. Bolt-ons won't do much good at this point... you need to get your setup straightened out before you build it more. Your hull may not even LIKE a droop and may slow you down. Or it likes a droop with a 2* wedge (or 4*). All this is part of getting speed from maximizing your setup. I'm at 75 with a .040 over 460 with a Comp 282H cam, Stealth dual plane, 8.5:1 motor in an open bow with an E pump. Keep in mind each change you make in hardware affects your setup and the process starts over. Welcome to the jetboat zone... test, change, test, change, repeat.
