    super charged 340 ???

    Too much compression with pump gas, i would think? You might be able to swing some thicker head gaskets to help some with that? You'll be changing the whole character of the engine you have now, so keep that in mind with what you're looking to do...Power vs Drivability vs cost? One plus might...

    under driven pulley dealer

    Are you looking to slow it down, speed it up, or just experiment? Does the manufacturer offer some different size top pulleys? I'd think I'd look there first.

    Boost referenced timing retard

    Not cheap, but looks like a good option for you Scott. As I said before, i'm not boost savy, but i can see you'd have some more left with that box especially if you decide to step up the pressure a little further.

    Boosted 451!

    X2. Your car looks great!!! Please document your turbo mounting with pics. I've see a few GM jobs, but it can really help some Mopar builders if they want to give the rear mount a shot. Very Cool......:thumbrig:.

    Anyone running a Paxton on a 340?

    I'm not a forced induction guy, but a quality ignition with some form of boost referenced timing retard will be your friend.
