They are very similar to some of the volkswagon engines used in the 80s. I don't have a picture of one on my computer to show you. The have a rotor head that looks almost like a distributor cap with injector lines instead of spark plugs wires. I think if someone is going to use one without trying to get over 350hp and 850ish on torque the VE is the way to go. The P7100s are great at big power but that is not what he is after.
I would get a Mitusa or Fuel boss before I spent the time to change a cam out.
I agree Mitusa is an excellent pump from what I have seen from friends that run them. They weren't out when I changed my cam. I was FASS, Holly Blue, BD double pusher set up and I think Bully Dog had a double as well of which all had issues at times. Last I heard was that folks were having pretty good luck with the Walbro set up similar to the Ford applications.
I've got a friend that run's an Air Dog on his drag truck and had some issues at first but they worked around it and it supply enough fuel now. I think in general Air Dog had some issues at first but I believe has them ironed out at this point.
If I had to do it all over again I think I might do either the Mitusa or Walbro pumps for a little more cost effective solution, however I do like not having to worry about fuel supply anymore with the mechanical lobe driven and time tested lift pump I have.
