Have you driven it yet?
I built a 383 hot street and strip motor for a customer who became a friend that had bought the Eddy STR and a pair of either Holley 600 or 650 D.P. carbs, I built it based on him using a good race converter, good ignition, fuel system and 4.56 gears in the back with short slick race tires to fit his 1963 Dart 270. He got in a rush to drive it and ended up with a stock converter, stock 2.43 gears in the 7 1/4 rear end with tiny rear tires and stock fuel system
That combination was very lazy below 3000 RPM but once it got above that it would set you way back in the seat
Good luck on your use with this set up
