I need to replace my original 1996 302/5.0L connected to the Mazda 5 speed OD manual transmission. I cannot afford $8000 for a Ford manufactured engine. I'm seeing crate engines for $3000 to $4000 but they all come with a carburetor. Is a rebuild better? If you have gone through an engine replacement/rebuild please share your experience. Seems a carbureted engine would be much more simple to maintain. Thank you for helping.
