Two of the biggest challenges in converting a carbureted intake manifold to fuel injection, are the correct installation (and the exact placement) of the injector bosses and the fuel-rail stanchions.

We faced these very challenges a few years ago, during development of our Boss 340 engine. Our buddies at Wilson Manifolds carried us through that dark time, setting up two "Boss" intake manifolds (an original '70 Boss 302 piece, and the other, a very custom, open-plenum manifold), with injector bosses (bungs) and fuel-rail stanchions that brought the carbureted manifolds into the EFI age.

Back then, it wasn't widely known that Wilson Manifolds provided this type of service for those with EFI interest. Times certainly are different now, as Wilson recently announced it is offering this convenient, intake-mod service to help engine builders and racers.

Ft. Lauderdale, FL Wilson Manifolds is offering a new service: the installation of injector bosses and fuel rail stanchions on intake manifolds. Aimed at the street-strip, drag racing, and off-road markets, this service is particularly convenient for hot rod enthusiasts, racers, and engine builders who are converting to fuel injection.

“To obtain efficient atomization,” says Keith Wilson, “the injectors must be positioned precisely in the intake tract. If not the fuel mist collides with an intake wall and vapors degrade into large droplets. In doing so they enter the chamber in less than perfect form and power is lost.”

Wilson, renown for improved airflow, air-fuel distribution, and horsepower gains via their ported and sheet metal manifold designs, spacers, fuel rails, elbows, and throttle bodies, says that they adapt existing manifolds or supply new manifolds with all necessary provisions for fuel injection. Porting work, nitrous provisions and burst panels can also be provided if necessary.

The two most popular fuel injection throttle bodies currently in use are the 4-barrel style and the large single-bore style that functions with an elbow. Four barrel throttle bodies are popular on naturally aspirated street-strip and Baja engines; large single-bore units are commonly used on drag racing turbo and supercharged applications as well as large displacement or powerful naturally aspirated engines.
