Ohmigosh!    That's the first time I ever got in trouble trusting Carroll
Smith!
His books have been the racer's bible for lots of years:  Tune to Win,
Engineer to win, etc.   My quote was from page 181 of "Nuts, Bolts and
Fasteners"

    "National Tapered Pipe (NTP) numbers refer to the inside etc., etc. . .
."

It didn't SOUND right, but I don't usually argue with Carroll Smith!

Thanks for the correction . . .  the basic taper tapping advice still
stands.
