EFI recommendation

[mitch_04]

I am looking for some recommendations as to which EFI people prefer. My father has a 67 Firebird with a 455 estimated at 500 hp, and wants to swap it to EFI. I am currently in Kuwait on deployment and would like to get everything ordered so when I get home I can install everything. I've been doing a little research but the internet available to us leaves a little to be desired.

Any info would be helpful. Thanks!
