A buddy of mine is building a 36 Ford two door sedan with a 350 Chevy, 700R4 and an El Camino rear end with 2.41 gears. According to the RPM calculator, with 29" tires on the rear, it will be running 1385 rpms at 70mph. He asked me if that's too low. Will it run there or be a total dog? Will it get decent gas mileage at 1385rpms or will it dog down and keep down shifting out of overdrive?
I don't know much about the Chevy setup so I'd appreciate your thoughts.
Thanks.
