What model year did Marine power start using EFI on 5.7L engines. Why do some people call these vortec engines/

"I can't say when Marine Power started with the EFI but the Vortec stuff came out in the mid 90's. It's the basic small block modernized. I think the wikipedia article covers the history pretty well. big improvements were head redesign and use of the roller cams. BTW, some marinizers offer the vortec blocks with carbs, today."

"Thanks for the info. These engines are some of the better running marine engines I've seen. I was just trying to yet a handle on the jargon, and I hadn't kept up with the differences."
