Here's one example from Brent's site (http://www.lykinsmotorsports.com/dyno.html): 445 ci FE, 525 hp @ 5500, 588 lb-ft @ 4200. 4.080 x 4.250, Scat 9000 series crankshaft, Scat I-beam rods, Racetec pistons, 10:1. Comp Cams custom hydraulic roller cam, 235/241 @ .050", 110 LSA, .610" lift. Survival Motorsports as cast cylinder heads, Performer RPM intake, Quick Fuel HR-750 carb. Stuska dyno.

390 is 4.050" bore, so above example is 0.030" over. This looks like a good, streetable engine to run on pump gas.
