It is an iron block 390, 6.0L block bored .030, offset ground crank (3.822" stroke), 6.125" rods, diamond pistons (~11.5 to 1), fully ported 6.0L heads.

Cam, something ~ 246 dur @ .050, .614 Intake, 240 dur @ .050, .609 Exhaust, XE-R lobes.

All boltons, Yella Terras, some kind of intake (FAST, FMS, etc), would 500RWHP be possible? What iind of TQ could this produce, 460-470? TIA, Shawn

Probably about the same or a little less than a Big Bore would with the same heads and same cam.
