Holley 1920 replacement

I went thru ~3 rebuilt Holley 1920's on my 1969 Dart 225 over several decades before I got one which made it idle like a kitten. The others must have had clogged metering blocks since they idled lean and stumbly. No mechanic could diagnose it, saying "valve job", etc., which I did to no effect. Finally, when a rebuilt long-block ran as bad, I tried a 4th carb and bingo. If you want to go big, a 4 bbl aluminum intake (Offenhauser) with a small ~370 cfm carburetor would be neat, or keep your eye on Gil Welding's new EFI intake and forget about old carburetors since even the best ones still have bad fuel distribution in a slant intake (as would TBI).
