well you know all a motor is a air pump the faster you get air in then out the faster your going to go along with fuel and spark i just bought a ram air kit from warpath resto. parts carb pan cover, carb pan, hood pan, air filter,vent tube filter, and the two foam seals and wing nut to hold it all together for 600.0 and its all steel and it all nice fitting and it looks awsome sitting on the motor i think its worth the money
