All Mopar \6 Fuel Injection?

You should be able to make your own EFI manifold without much trouble. Pick up a new/ used 4bbl manifold, and look at my thread --Kit Carson posted how to use 1/2" tube x 3/8 pipe compression fittings for injector mounts. I had to turn them out a small amount to fit the injector. You need to get them in a straight line if you are going to use extruded fuel rail, but you could get accurate enough, if careful, by building a fence on your drill press, and mounting the manifold on a "sled" so that you can slide it back/ forth on the press. Since /6s have an "even" edge where the head flange is, this should be easy. See here:

(One of the pages says 3/8 compression x 1/2 pipe but it's the other way around)
