if it don`t have much grunt from take off, a single plane is only going to make it worse. for your combition, a single plane would be beneficial in the mid and upper rpm ranges as your engine has. but on the street it`s not horsepower that moves all that sheet metal, it`s torque. you can bet the single plane is going to cost you a 10 to 15 ft lb drop in the lower rpm ranges and if horsepower increased in this same area it`s not gonna help it any. it`s your car and your call, lower gears or a higher stall maybe needed with the single plane intake, as well as the fact you have a small cubic inch engine which with high RPM isn`t gonna have much low end to start with. if your racing it in the 1/8 of a mile, anyone with torque and decent gears is gonna eat your lunch. also keep in mind if you go with a single plane, one cylinder is drawing off the entire mass under the carb, so less cfm is acceptable and would likely be beneficial. your call. good luck.
