Has anyone measured the casting thickness on this. I see some potential areas where it could be machined slightly smaller that might help with fitment.
I look forward to seeing your results. I may just have to make this work for me with the price as good as it is.

The more and more I use this intake, the more and more I hate it. Edelbrock did so many things wrong. My Lucas 42# injectors hit the fuel rail mounts which then causes the fuel rail to **** backwards. It pinches the fuel injector so tight that it cannot spin freely and looks like it might be cocked enough for o-rings not to seal. This intake really needs the skinny injectors for the fuel rails to fit correctly. I'll find out in the next day or two when I finish swapping fuel injectors/rails if the o-rings leak on the fatter injectors. And the fact that Edelbrock did not include the GM 90mm throttle body pattern and made up a new LS1 style fuel rail with different mounting holes. They made it insanely hard for anyone to switch to this manifold its ridiculous. Although it did put down decent numbers, see my previous post for dyno graph. I really wish I would have stuck with the FAST intake instead of switching to this.

i used the fat injectors on mine. Just grind down the area near the mounting holes to give clearance. Also it was quite easy to make mounting tabs that i welded to the rails and bolted to the mounting holes edelbrock provided. Mine will be running soon but i won't have anything to compare a before and after... I will say it pulls more vacuum at idle compared to the stock LS1 intake (for whatever thats worth)

Just confirmed that the fat injectors do not fit. I ground down the mounting brackets, and the fuel injectors still hit. I started the truck and it is indeed pulling a vacuum leak around the bottom fuel injector o-ring at each mounting bracket.
Very very poor design.

Those are the injectors I'm currently using. Delphi/Lucas 42# injectors. They do not clear the fuel rail mounting bracket. I did some more grinding to the brackets and got as close to the mounting holes as I was comfortable as doing and the injectors are very close to fitting. They still rub the mounting brackets, but it looks as if the vacuum leaks on the bottom o-ring injector are gone.
