1974 302 on an airboat
new pistons, bearings, cam,...everything. runs great. tachs 2800 rpm wide open. i need 2-300 more rpm. evrything is stock. the carb is a d4te la. anything i can do? an airboat propeller holds the motor back. i can adjust the pitch of the blades, but if i go less pitch...i go slower. i want to be able to put a little more pitch in and fly!
