Dodge 1500 2002 5.9 Magnum Camshaft Flat, Roller, Hydraulic Roller

Kerndog is on it!

IF you want to use that Hyd/solid cam in a roller cam engine, you will need (of course) the matching lifters and new longer pushrods.

It would be much easier and quicker to get a roller cam and re-use the roller lifters. IMO, also get a new timing chain.
