50ADRod: If you want the LS series engine, but aren't hung up on having the EFI, BOTH Edelbrock and GM performance are now supporting carbureted intake LS engines, that continue to use the coil packs and reluctors, via an MSD blackbox ignition kit.
This is a FAR simpler installation than the EFI route.
The end power is not worse or not better - virtually identical everywhere in the RPM range, but I suspect that the fuel mileage on the carbureted versions is not as good. I don't know HOW MUCH not as good.
This is ONE route that I myself am considering on my SLURP project, posted on this website.
