kenny,are you using a nose cone? On my 272 i'm turning a 30 pitch 4 blade labbed prop around 5400,this summer while i was waiting for parts for my outdrive i bought a spare drive w/out nose cone and the boat felt like the nose was digging in,boat was hard to get trimmed out enough to loosen hull up. My hulls a 2000,ive had more problems with chinewalking above 70 than anything,full hyd strng helped take most of that out. Do you have a pic of your boat at speed,it really needs to be on hull pad towards back to air out enough to get good speed. I'll try to post pic if i can find one,Smitty

That pic is at about 80mph without a nose cone,everyone i boat with says when i'm going mid 80's i only have about 2 feet of hull in water and that it almost looks like just the drives in the water. I haven't done anything to rear edge of hull yet,everyone says these bajas will go 2-3 mph faster without it BUT that it greatly increases porposing unless your dragging your trim tabs,Smitty

I started out at 63 mph was out of the box speed, I started with a prop change, made 65, Then the headers, cam change, ported the steel heads, prop change turned 70. Next I was looking for 75, I didn't want to put a blower on it, I wanted to see what I could get out of it naturaly asperated. I started modifying the intake manifold, ported the s___T out of it, hand made a plenum, bigger injectors, tossed the vst setup, put some big a-- throttle bodies on it, a nasty solid roller cam, stroker crank, bored it and turned 77. Now still not wanting the blower, I'm lookin for 80, I think the hull is in need of a little TLC, so thats next, we will see what happens after I take a belt sander to it! There is potential to make the 502 run and run better, but there is some attention needed to the stock intake, fuel system and heads. Not knocking the blower motors but you can get speed to a point without one! What the heck else is there to do in the winter anyhow?

Kenny,how loud is your boat? I imagine you must be running dry exhaust with that big ol cam. I have lightning headers on mine and the molded swim platform seems to muffle it alot,at least from the drivers seat!How tall of a prop have you tried,with the kind of torque your making i'm surprised your not spinning a 30 or 32 pitch,Smitty
