Magnum 360 mods

I generally don’t modify anything in the magnum oiling. Blueprinting the pump is a good idea, measure the lifters and lifter bores for excessive wear, and set the bearing clearance where you want it (not just slapping bearings in the rods and mains) will serve you to well above the hp and rpm of a “driver”. Last thing is make sure the cam bearings are good, you can loose a lot of oil around a torn up cam bearing and magnums tend to tear them up.
