89 360 engine

To be a hydraulic roller engine, it usually needs to be out of a HD truck, as in 3/4 ton or larger truck, van, or a Ramcharger. A cell phone camera pointed down the distributor hole will at least show the back of the lifter locator spider. But a very good base for a build. A cell phone bore scope camera to look in the cylinders would be a good investment.
This may be true, I don't know this statement to be incorrect. It was my understanding all 88-92 LA 360's were roller cams though. My personal experience is that all 5 of the engines I've had in this time window were roller engines. Going to pick up another in a few days. For a disassembled engine I'd say 100-150 bucks.

These are a great platform to build upon. These later blocks usually had better machining tolerances with less core shift than older ones. The efi prevented cylinder wash down from running rich on the choke. The ones I've pulled apart had little bore wear, most had cross hatch still visible.
