as far as stock puch top ends go, which is better for performance? i'm guessing the korado top end is better simply because it is newer, but the magnum puts out 3.5 hp stock or 4hp with the intake derestricted. then again i'm guessing the korado has way bigger transfers and it has the stock boost ports. anyone know differences in intake and exhaust port size between the two? or just which is better?
