I have a manual, so things are a little different. I did longtubes with cats, ported stock intake, ported ZL1 throttle body, and E85 with a tune. Sounds crazy, but something told me from "hotrodding" my many other cars (LS1's and Mustangs) that it might change it in a way I don't love. The trade off always seems to be a loss of bottom end and adding some herky jerky throttle response, which is what I have felt. I will I'm sure enjoy it the next time I do a HPDE event or drag myself to the dragstrip. My feelings will probably change then. I don't even love the sound, it has that clapping/whatever it's called sound when you go WOT and get up in the revs, just like my 2015 Mustang GT did with catted longtubes. As long as I stay below 3000 rpms, it sounds cool. Even my wife said, what happened to how good your LT1 cars from the 90's sounded? I kept the stock NPP exhaust.
Going cam/heads in these cars is so much more money than my LS1 cars, but the gain and baseline to begin with are so much higher. Granted I had to much cam in my daily driver 99 Z28, so the surge was my own fault for listening to Futral Motorsports. Then you could debate the drop in piston and rod combo and go Procharger.
