Rarity (and desirability) of a slant six/ factory 4 speed?

Keep it and run it. Diod you know there are "perfomance oriented" /6 folks around? Ive seen holley 4 barrels on slants. I knew a feller who would swear that he can lay rubber for a city block with a 71 slant 6 valiant.

See post #59. Car was already gone before he had a chance to see it in person.
