I think he had 2.73 gears out back with a wide ratio four speed. The car would've worked better with a 5 speed but it wasn't in the budget at the time. It also would've been much better with EFI but once again, that wasn't really in the budget back then. These days a simple Holley Sniper kit would be the way to go but back when this car was built there were not any budget friendly EFI kits on the market.
