Gear Ratio and RPM deciding on gears

Not talkin about the OP here, BUT.........

I know I've preached it till I am blue in the face. People come on here wantin to know "what gear" or "what converter" is best. They have (for example) a 340, 240-260 @ .050 cam, all the goodies and then curl up in the fetal position like a little sissie when I say "3600-3800 stall and 4.30 gears".

If you're gonna build one with "all that" up front than "what's out back" needs to match.
