Even though the engine sat uncovered with the heads off for years, the bores on this 200,000-mile engine showed very little wear. One of the advantages of late-model fuel-injected engines is that they suffer from much less ring wear-normally a by-product of fuel wash down at cold start-up on a carbureted engine. We don't know if this core started its life as such, but when selecting a budget core, an EFI engine will typically show less bore wear than its carbureted counterpart. Despite some minor pitting, Kauffung figured there was life left, and just replaced the dished pistons with a set of budget Federal Mogul hypereutectic slugs. Bore prep was limited to a hand-scuffing with some sandpaper.
