A PS....
I'm using the Pure Power cleanable billet filter.... it has magnets inside and filters 100% of the oil. It is NOT a bypass filter... it's a 100% all oil goes thru this bad boy filter...
The magnets and the 100% filtering is what saved the crank - the bearings and all the other "internals" in the 427 when the cam was being eaten by the roller lifters... Or at least that's what the engine builder said. Having it cleanable is also how I could SEE that the motor was going to bad... so now I'm double sold on using this "type" of filtration.
