I'd say allot depends on who built & assembled it, who did the porting etc.
Maybe go google & Comp Cams get their CamQuest6 {IIRC} download,
it'll give you a ballpark idea, IMO it's not that far off, from some of the stuff I've done,
mostly basic stuff & around what cam of theirs will best suited, rec. lift & duration,
solid/mech. lifter, hyd. lifter, sol. roller, hyd. roller, etc.
but you can change a few of the variables too...
what type of usage ?
{street strip choppy idle, drag race only, w-race converter etc.}
what compression, head cc, cylinder volume ?,
{pocket ported, fully ported, valve angle, stock etc.}
what valve size int. & exh. ?
{even has an optional cfm graph etc.},
what make of engine ?
{383-440 wedge, 426 hemi etc.},
what type of added mods ?,
{N20, blower, turbo etc.}
what cfm carb or inj. size ?
{cfm makes a world of a difference},
what style of induction ?
{port inject., efi, multi-carb, tunnel or single carb, single or dual plane, ported etc.},
what exhaust ?
{Stock Manifolds, header size tube, w-mufflers or open headers etc.},
but not really based on strokers thou
Perfect world scenario maybe a formula 2.2 hp/per cfm of cylinder-head flow
342cfm x 2.2 = 752.4 realistically 550hp- maybe upto 750-800hp @ sea level
{but of course professionally built, even what fuel is used, methonal, ethanol, race gas etc. & by someone who knows how to properly put together a good package/parts etc. & what they're actually doing}
should be a no brainer, properly spec'd/built/assembled...
good luck & happy Moparing
