      That would look cool sticking out of the hood

      Very nice!
      We have an Enderly one and it also came off a drag boat. Seems that's the place to find em.

      Di you get the pump and the timing cover with it?

      My bad I see yours is EFI, ours is MFI.

      that is sweet!

      Thanks guys, yes EFI through the hood is the plan. The pics are all mock up, it was never run, guy had to sell and recoup what he could.

      was just thinking about how you run an Idle Air Control valve on an IR intake. Does it have some sort of injection tube rail to each runner or a linkage kicker like a Dodge TBI? Wild! Boats would seem to maximize the "All or none" personality of a mechanical injection, but EFI would smooth that right out.

      I’m not sure exactly how it works without an IAC , but I’m pretty sure it really just uses a TPS, Map, coolant temp, O2sensor, Air temp, EFI dual sync distributor, unless I’m missing something. The whole setup from Hilborn is over 7k.

      I've got EFI on my quad four engine in my race car. To keep the old time look I use side draft webers as throttle bodies. I don't have an IAC, I use the idle adjust screw on the carburetor to control the idle. It works just fine. IMG_0299.JPG

        Love the old sprints. Don’t recognize that engine though.

        There is a guy here in Cincinnati rebuilding vintage sprints. Works on a lot of offy stuff and he drives the wheels off some of them. Amazing era of racing.
