GMPP Carb to EFI Conversion I've searched through many threads and saw what was needed for the conversion. I'm still confused on mounting the injectors, do you just drill out the bungs to a certain size and plug them in? How is it done?
Are custom fuel rails needed, or do off the self ones work?
Also, do any of the sponsors sell a manifold with rails and drilled bungs already?
Do you guys think a nitrous built (200-250 shot) 370ci would benefit from this free flowing intake using a nitrous plate setup?
Sorry of these questions are redundant, I can't seem to pinpoint these answers, ..thanks.

on my HSR it looks like a counter sunk hole but i think there has to be a space for the seal to "click" into ant seal it so fuel doesnt spray everywhere. jus take it to a reputable machine shop and tell em what u wnt.

I had my machinist here at work modify my GMPP intake, based off of an LS1 intake. I used the Speed Inc. fuel rails and custom made some stand offs, the GMPP intake's injector mounts are too short compared to the LS1/LS6 intake mounts. No one as of right now sells a pre-drilled and setup GMPP intake package, would be nice though. Your application would work very well with this kind of setup, you might be better off running a 4-bbl EFI throttle body vs. an elbow and single blade throttle body ... since you will be using a plate system.

Edelbrock sells a pre-drilled version of the Victor Jr LS1 specifically for this. It's PN 29086 with fuel rails or PN 29085 without fuel rails. The fuel rail kit is also available separately. They should be shipping now.
