Q-jet. The truck avenger isn't close, but it's better than the Edelbrock equipped with the off road stuff.

They are out there. It's that or go to a TBI style injection system. I wheeled a lot with my worn out 350/q-jet and it never failed me. Didn't matter the altitude or position pointed up or down, side hill or not. It always ran, never stumbled. Only things I would do to compensate for the extreme altitude where I was (8,000-13,000 ft) was bump the timing a little and give the carb a little faster idle. I wouldn't mess with the mixture. So it ran a little fat at altitude due to the lack of air, but it also meant it was one less thing to change back when I got home to the lower altitude.

I've seen the light and gone EFI with my LS swap though. Which makes the thought of going back to carb on anything off road much much less probable.
