If it has a metering block in the rear someone has converted it, good mod for racing, you're already a step ahead
A more advanced mod is to thin the throttle shafts and install button head allen screws to hold the blades to the shaft in place of the stock big brass screws, but you need to know what you are doing and have good mechanical/fabrication/machinist type skills or a steady hand if you do it with a Dremel. Requires disassembly of the baseplate/butterflys. this and the choke tower mill will give you roughly another 50-60 cfm.
