Have you read the discussions on EFI? There are probably half a dozen over the past 6 months. Search can be your friend.

But why??? What problem are you trying to solve? What do you hope to gain? I assume you are considering changing from carb'd. What do you think the gains will be vs the cost?

If you already have an older generation EFI system and want to upgrade then there have been many improvements that probably make it worthwhile, but even then cost is a factor.

If you are in AZ in the Phoenix area and only rarely go to higher altitudes EFI will do nothing a properly tuned carb won't do. If you put in an EFI system and don't "go all the way" to the MAF based system (utilizing full tuning feedback with O2 sensor) then you've got nothing more than a glorified electronic carb that cost you another 4K.

If you're considering the 8-stack the faux 8-stack with EFI is your only choice since the only thing below converting to EFI for the wrong reasons is a true Weber.
