Do the pop off valve. The one I have has a 3/4” milled plate because the first one blew lol. The bottoms are different, single has no divider 2 carbs has the divider. I’m not sure how it would work with injection since it was designed for mixing gas and air in the intake. It is a cool looking intake and was the go to back in the day. Either way you’ll have to run spacers under carbs so linkage ent hit (hood clearence)
