Upgrading my 340

I will agree with the above except "Fashion statement" for a 6 pack.

The efi would be better on many fronts for drive ability and tuning chore(s) that will have to be done on the day you install it.

From a power point, the 6 pack is approx. equal to a 950 cfm 4 barrel carb. I'd bet the efi has more air flow capabilities. But the engine, on the other hand, will only consume as much as it needs. I doubt ether system is a short fall.

A bunch of whiners will allways complain about tuning a 6 pack. It is not an easy thing and down right hard if you have never had one much less ever tuned a carb. Against the efi, it is a nightmare by compare. Since the efi is plug in and go play. And that is huge and that is why it gets my vote based on what I read from you.
