    Edelbrock did offer a TBI retrofit intake that reused the 7747. I imagine it worked similar to what you're trying to accomplish but keep in mind that the pico injectors that came with the kit was designed to be batch fired with a 7747. Someone smarter than will chime in if you can batch fire the stock TPI injectors with the 7747. My guess the injector driver is gonna fail in short time. Corvette= Y-body Camaro/Firebird=F-body

    There's a few ways to skin a cat...consider a '7730 or even a truck PCM '427 w port mod...

    gotcha. I'm pretty sure these are batch fire. I found a wiring diagram last night for the ecu that is supposed to be in a 91 vette which I believe is the 1227727. and the diagram only shows two injector drivers.

    I think it will work?

    I put a tpi intake on my 93 k1500 and used the ecu from the truck. I spliced in the injector plugs it to the stock wiring harness. I used the tbi heads but i ported them and i have stock roller cam,lifters and roller rockers. It runs good im waiting on a chip to put in the ecu.
