470 Stroker - Anyone built one?

Wow, it doesn't have to get very complicated. Admittedly the example I'm going to use is of a 493 but a 470 won't be far off.

We built a customer a 493, 10.3:1 compression, very mildly cleaned up Edelbrock RPM heads (not even what may be called "Stage 1"), Erson hydraulic flat tappet 236/244 @ .050", .567"/.567" lift w/1.6 rockers, Edelbrock RPM intake, old 850 Holley.

566 hp @ 5,300 rpm and 630 tq @ 3,500 rpm.
