Remember when stand-alone EFI systems seemed beyond the reach of the average car guy? Oh sure, the computer geeks could get it to work, but for those of us without a computer degree, the risks just seemed to outweigh the benefits. Well, now that the EFI companies are well past their infancy, anyone who really wants to take a bit of time to learn about them can have a great performing EFI system in as little as a weekend.

But what if you don’t want to run a single or pair of four-barrel throttle bodies? What if you have (or want) a Six-Barrel car and want to keep it that way? And what about using a Shaker hood?

That’s the issue that Muscle Car Restorations came up against recently, when the owner of a ’70 Challenger wanted to upgrade from a 383 four-barrel to a 512-inch stroker and a Six Pack. Sure, repop carbs are available, but EFI on a six-barrel throttle body sounds cool.

It just so happens, that Bruce K. Bridges, founder of F&B Performance Engineered Products, has been working with Chrysler two-barrel throttle bodies for well over a decade, and has been building billet aluminum versions for some time now. He has come up with a complete six-barrel setup that will work with either FAST’s XFI or EZ-EFI systems. Just like the original Six-Pack cars, you can run around on a mild two-barrel and still have as much as 2,300 cfm at your disposal.

Because F&B builds their throttle bodies from billet aluminum instead of cast aluminum, they can offer bore sizes of 44-50 mm, and claim that they will flow more air than any other throttle body of the same size. The billet construction also allows them to build-in larger inlet areas than stock, use tapered flow paths for maximum ram effect, and most important in this case, they are compatible with factory air cleaners and shaker hoods.

F&B also supplies an Edelbrock Performer intake that has been fitted with the proper injector bungs and vacuum ports for the MAP sensor and etc., so you can get a complete bolt on kit that even comes with custom spacers so your shaker hood will end up at the correct factory height. You will need to upgrade your fuel system, but we’ll show you what you need to do to for that as well.

So no longer are you six-barrel guys left out of the EFI loop. Whatever your application, contact F&B and they’ll set you up with what you need to enjoy the full rush of six barrels with the precision of modern EFI.

Cost for Six Pack EFI: starting at $2,650
