Slant 6 EFI

I think FI Tech uses common MPFI injectors in their throttle body, so fuel flow depends on what PN injectors they install. Also of concern is matching the air flow to a slant. It will be hard to control if you get all the air the slant can use at just 1/4 throttle opening. But, 3.7L is hardly a tiny engine, and many new V-8's are that small.

Too bad the Jeep 4.0L six intake doesn't bolt up to a slant head. That would be an easy way to get MPFI. Unfortunately, Chrysler dropped the slant before MPFI became common. That Jeep block dates back even further to the 1950's and is as loved as the slant.
