This sounds pretty cool, wonder how much difference this would make on ZZ4 with aluminum heads,Hedders and MSD ignition, anything real noticeable?

What about older motors, like a 283?

The real advantage of EFI is cold start up, drivability, and better fuel economy. WOT power is rarely different between a properly tuned carb and a peoperly tuned EFI system.
