What will my 340 run? and what intake and carb?

Well Matthew, I'd say your being realistic on the 1/4 mile times that you would like to achieve. Id say that there is nothing wrong with the intake and carb. that is presently on the motor. Is it just a stock cast iron and thermo quad?? I'm not really experienced with the 340's. I've never owned one. But with what the motor has in it I'd say that the 13's should be realistic. Another, Matthew
