Will a 2000 ford 3.8 mustang engine fit into your 1998 with 3.8?
Yes, a 2000 Ford 3.8L Mustang engine should fit into a 1998 Ford Mustang with a 3.8L engine. Both years used the same basic engine architecture. However, there might be minor differences in accessories (alternator, power steering pump, etc.) and potentially some wiring harness differences. You might need to adapt some components to ensure everything works correctly. It's not a direct bolt-in swap guaranteed to be completely seamless, but it's highly feasible.
