Same concept as the hi-ram just shorter. Injectors wouldn't have a special part number, as Holley doesn't know what your fuel system requirements would be. iirc they use the standard tall-body injectors like most of the non-truck LS engines, and pretty much every aftermarket company will get you one in any flow you need.

You probably don't see it used much, as I don't really know what gains are to be had. The hi-ram has some gains, but its biggest benefit is cool factor and a love of teaming with some additional atmospheres.
