5.7 Hemi Stroker

Most of the builds I've seen were + 50 rwhp on the top (some more), and +75 rwlb/ft torque across the curve down lower. This would be a conservative estimate, but time and again, that's what guys on LX forums saw. This is assuming a 5.7 to 392 build. The K1 stuff should be GTG, but I'll have to check again with my guys who have built a few dozen of these which crank usually requires the least amount of heavy metal to balance (though I recall them saying they all require more than the 6.1 factory cranks).

I'd say 500 rwhp would be a good goal for a 392 stroker, assuming ported heads, good cam, etc.

I'd call up flatlander- they have a k1 kit with bearings and all for $1969, add balancing for $299. That's tough to beat.
