Need Help on Magnum 360/380 hp Crate Motor Tech Info

The roller wheel eleminates most of the issues. But there are other parts that wear and hurt the rollers lifters.

The factory FInis an excellent unit that keeps the inside of the engine in great shape. Many here have reported near perfect cylinders with cross hatch marks still seen on the cylinders after many miles. I myself reported this on a 80K 5.9. Others have reported this on higher mileage engines.

Use of a carb doesn't have the FI quality and contaminated oil results due to fuel, carbon deposits getting past the rings will sooner or later get into all the small places of the engine.
