Im thinking of changing my intake setup on the 6.0 LS thats going into my pro touring Malibu. The engine is all done, and I have converted it to a carbureted intake (Edelbrock), and then instead of the carb, I have a FAST EZ EFI 2.0 setup Iwas going to use. Now, I'm contemplating using a factory LS type intake, and going with MSD's Atomic EFI setup. The car will be 60 percent street, 40 percent SCCA type event car. I plan on autocrossing it pretty often. So, for you LS guys, ultimately, will there be a drastic difference in terms of drivability? I think the horsepower edge might ultimately go to the setup I currently have, but you think the LS type intake would be better? I could go either way I guess...
