Welcome!

Electrically, the wiring is the same for an inline-6 and a small block V8 (such as the 283).

Physically, there are some differences in the wire length and routing for the engine harness.

Also be aware that there are wiring differences between trucks with a warning light style instrument cluster vs. the factory gauge cluster. Those differences apply to all engines.
