I have a 20 foot VIP valliant with a small block 350. Last summer i gave it a set of edelbrock performer RPM aluminum heads and a wiend single plane alum intake and a set of EMI thunder performance manifolds. but I never got around to caming it and geting a new carb. I was thinking on a demon 750 and a cam in the upper 400s or so. the stock cam in it is a 401/410 lift, but I need some expert advice on what to buy. Rt now it turns a 23 pitch 14 3/4 inch prop at 5300 RPMS at 64.9 on gps. Im wanting to turn a 25 pitch at 4800 or 4900 rpms it will only turn the 25 at 4300 rt now.
