3.55's dont help..

have you tried a larger discharge nozzle/squirter?
if not, try to find a buddy that might do some tuning on carburetors and see if you can try a couple different sizes... just go 2 sizes bigger than what you have to start with. this will give you a lil out of the hole..

what kinda torque converter do you have? that would be next, unless you have a decent stall converter already..

check timing maybe?
