But the 6 Pac carbs are a turd to keep working well. The KISS approach is where it's at. A Edelbrock carb is easy to tune and will go years with no adjustment.
If you are familiar with Holleys it's not hard to keep the 6 packs running... You just treat them as a vacuum secondary 4 bbl with an extra set of secondaries...
Throw in the short yellow spring in each secondary pod, adjust the linkages so they are synchronized together and let-r-rip.....
