Does a 1995 350 CID in a 2500 pick up have a roller cam?

No, a 1995 350 CID engine in a 2500 pickup typically does not come with a roller cam. Most 350 CID engines produced before the mid-1990s used flat tappet camshafts. However, starting in the mid-1990s, many GM engines began to incorporate roller cams, so it's essential to confirm the specific configuration of the engine in question.
