Your 3x8's 24" on center are the same as todays 2x8's 12" on center. Even better, as yours are probably a full 8 inches, rather than 7 1/4 inches. An actual 1.5x8" is 34% stiffer in bending than an actual 1.5x71/4" . This would be the equivalent of todays 2x8s 9 inches on center! Yours being solid oak doesn't hurt either.
I don't have a code chart for max spans handy, perhaps Steve or someone else does.
Good Luck,
Merry Christmas!
