Re: Plans for a 478 build.
For fuel injection on the 305 you can go with the Howell TBI most likely a 305 Chivy unit along with an HEI. I talked to Howell a few years ago and they said it would not be a problem with the 478. They do highly recommend running an HEI with it

Did they say what ecu they would use to drive the injectors on the TB? Although aftermarket standalone controllers are nice, I like the idea of retro-fitting a GM system on it. I have an extra Procharger head unit sitting around and I thought about looking into the SY/TY 1227749 ecu (keeping it all GMC) which could handle boost. The problem with the SY/TY setup is that it would require an intake manifold and probably some sort of crank hub mounted reluctor. Maybe it's time to search the third gen.org site.
