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

Ok then considering that Im guessing they have been gone thru since manufactured. They didn't come with 2.02s when I bought them, so I'm guessing "somebody" has worked them since made ... Mine came straight from EQ themselves.
That is correct, P.I.E went through them and installed the valves, guides, and the p&p work. It is to my understanding that there is a significant amount of flow and power that can be achieved just porting the exhaust side alone. However, and of course, I opted for the complete job on both sides. It costs a bit, but, where do you out a cap on good flow! LOL!
