Whats this? 383 Stroker, Oh Yeah!

I saw the headers in the pic and was wondering how you dyno'd it...lol.
I just delivered the 496 (4.25 stroke, +030) I just did. Small custom solid flat tappet as this is going to look stock with manifolds. Idles at 850 like a kitten. Dyno test will be in the car after the Musclepalooza in NY. I anticipate a similar torque curve. If we can even call it a curve.
Does that EFI come with the fuel pump/system or is it just the throttle body, controller, and wiring/sensors?
