Fired up the new crate motor and with a little tweaking, I'll be in the snow soon.... question for you air flow/carb people: Does the K&N "X" treme air flow top work like they claim?? Anyone with experience on this??? K&N claims a extra 525 cubic feet/min of airflow.... I have a new Edelb. Q-Jet 750 cfm, K&N filter with a comp cam, headers, and all MSD. Thanks......... HE will always get you out of the mire clay!!!
