it makes some sort of sense though... the 4.88's will give you moer torque at the wheels which might compensate for like 20 ft lbs that was lost in the decrease of power... i personally think the 450 with 4.30's would be the way to go since it's got the extra torque from the 4.30's plus the 350/650 at the flywheel so you're puttin out bigger torque numbers then any other configuration
