225 bogs taking off from stop while hot

Dealt with that in my first car for almost 20 years, a 1969 Dart slant 225. No mechanic could figure it out. I was sure it was due to being lean at idle. I finally tried a 4th Holley 1920 and it purred like a kitten. I had tried changing almost everything under the carburetor, yes even a new long-block, so figured it must be that dang carburetor. As related here, it has a sealed metering block for the idle circuit that gets clogged and most rebuilders don't touch it. Some guys here said they know how to clear those passages, blowing compressed air thru some of the holes in the base. BTW, other manufacturers used the Holley 1920, so might find the same issue discussed in Ford and GM owner forums.

If you give up on the 1920, a Holley 1945 should fit, though I don't know the pros and cons of those. A harder option, though nice, is to find a rare "Super Six" manifold to use the common Carter BBD 2-barrel carburetor. Another is a 4 bbl intake (Offenhauser, Clifford, or Aussie Hurricane) with the smallest 4 bbl carburetor you can find (~370 cfm). At the highest end would be an MPFI intake. A company in TN began making them for the slant. But that requires other things like high pressure (60 psig) fuel delivery. At least one guy here rolled his own MPFI.
