Fan question

I would run a thermal clutch and a 7 blade fan. As stated above, you need to understand your clearance before you spend money. The aftermarket radiators are usually thicker and are sometimes positioned closer to the engine the way they mount.

The magnum fan runs the opposite direction of an LA, so it needs to be matched to your water pump, belt system.

I have a nine blade magnum fan from a truck that I bought before I understood the difference. PM me if you are interested.
