Can you mod a spread bore Holley?

MBHD: I thought about this before but never actually tried it.
I too thought a spreadbore Holley would be good with it's small primary and big vacuum secondary.
Of course as Tom points out the 600's (and various unidentified 450-ish sized carbs) go cheap at flea markets.
But then I found a cheap 390 and forgot all about it. : )
