$108 shipped from www.neweraperformanceparts.com (where I got my gss340) for gss307 or gss340 . The gss307 is the standard pressure 255 lph fuel pump , it is efficient only up to 60 psi and will support about 500 hp , verses the gss340 supporting about 600 hp . You will be ok as long as you aren't using a power adder .

Personally I'd go with the 340. The data on http://www.autoperformanceengineering.com/ shows it consumes less amperage than the 307 at the same delivery pressure. All else being equal, that's reason enough.
The other consideration is that you'd be operating the 307 at nearly it's peak pressure...not a recipe for long life.
