You are right on the aero wing score. That costs more money and we were more interested in having a crank that could take a lot of N2O if needs be. Got a super nice looking Scat crank for the 600 inch BB I am building but the cost was way more than this small block 3.75 stroker. AS far as aero cranks worth our dyno testing has shown that above about 3000 - 3500 rpm differences start to show. At 7500 this can be as much as 6-7 hp for a typical wet sump motor.
