Is there someone that specializes in flex plates/ balancing that you know of? I'm running just over 300 hp and 310 ft/lbs torque and I plan on upgrading the rear end to either 350or 373 rear gears. I'm getting a lot of differing opinions on which way to go. The engine builder suggested the 3.73's other guys that I've talked to told me that the 3.50's would be better on gas and for any distance travelling.
