sorry...I was in KC for the weekend and just got home. Basically I'd say screw Holley and Edelbrock altogether and make your own. You can either buy an EFI intake or take a carb manifold and drill out the bungs for the injectors. You'll need to upgrade the fuel system whichever way you go to support more pressure and volume...Aeromotive makes some kick ass kits. But as for the system itself...I'd give Western Motorsports (
www.wmsracing.com) a call. They sell an insanely kick ass system called SDS Injection (see my sig) for around $1300 (the stand-alone kit). Just keep in mind they mostly do Ford stuff...but I'm sure they could recommend additional hardware to finish your install (throttle body, injectors, etc.). The system hooks up with hardly any sensors and installs in about 3 or 4 hours if you've never done it before. The big plus to the SDS is that it comes with a handheld controller...no laptop required to program it. Plus it comes with 1, 2, or 3 bar MAP sensors. The MAP sensor (manifold absolute pressure) measures pressure at the intake vs. ambient air pressure. Since speed density systems don't measure the actual amount of air entering the engine, it uses pressure to make an educated guess and adjust fuel and timing. As for the bars...1 bar = 14.7psi of pressure (ambient barometric pressure at sea level @ 32 degrees farenheit). You'll need at least a 2 bar MAP for a blower setup...3 if you want to go higher than 14psi. If you don't wanna mess with piecing a system together, I'd go with the Holley setup. It's more expensive (if memory serves) but at a glance it's more flexible and complete. Just remember that you'll need a laptop to program the thing if you don't want to use the default program. A really powerful alternative to the SDS kit (not a kit...just the system) is the F.A.S.T (Fuel Air Spark Technology) DFI kit. Almost all DFI kits are batch fire (the fire one bank of injectors as opposed to individual) but the F.A.S.T kit has options for wideband O2 sensors, sequential injector control, and even an individual cylinder control...it even uses a datalogger at 20 frames/second Again...you need to add a laptop to ther cost if you don't already have one. If you want any more info, feel free to hit me up in this thread or in a PM. EFI (or DFI in your case) can be a total pain in the ass to set up if you've never done it before.
