This is an electronic fuel injected 350. It features the Edelbrock 2 barrel fuel injection system for making big time torque at lower RPM's. We use many different types of after market fuel injection systems. If you don't want a carburetor, we can certainly design your engine to run nicely with an EFI system like this, but keep in mind, these systems cost considerably more than a typical carbureted engine. An EFI system alone will add an instant $2,000 on up to $4,000 (depending on the system and how complete it is), to the price of any engine. You've got to burn a LOT of fuel to make up for the cost difference between the savings you gain in MPG to the cost of a carb. In my book, it's hard to beat a really good carb, but if you want an EFI system on your power plant, that ain't a problem!
