I put a FAST EZ 2.0 on a 455/PerfRPM for a friend, and it has ran great for about 2 years now.
Another EZ2.0 inst on 350 chevy, Perf EPS also ran great. I added a 2" open spacer and no differences anywhere.
I plan on testing several different intakes on my own 455/efi, on a chassis dyno, in the near future. Right hand is in a cast now though, not sure when I'll be healed enough to do it
