Best Parts For A 1973 Dodge Dart 225 Slant Six Tune Up?

If you have a Holley 1920, search for info on blowing out the sealed metering block. One guy says he does this. Otherwise, a rebuild may not fix a lean idle. I got a low-cost kit of cap-rotor-plug wires at rockauto a few years ago. But read SlantSixDan's discussion of poorly-made distributor caps. Wise to run a dedicated ground wire to the case of your ECU box since bad grounds are a common problem. Someday you could retrofit to an HEI module for a slight spark improvement.
