the 2 fan idea can actually cause more turbulance than anything when front to back. if it were me ( since i already did it ) i'd invest in a summit racing dual core, all aluminum radiator, and an aluminum waterpump...i measured my frame rails and fabbed up brackets to go with the extra capacity all aluminum radiator, and threw on an electric fan for good measure...go with a lower T Stat too if you want...should help quite a bit.
