Get Vizards book on Holley, a bit dated in today’s world, but we are all dated, working on dated stuff so totally applicable. It is well written and just a wealth of info on Holley carbs.
His newest one just on Holleys has looked pretty good from all the excerpts I've seen. Very complete.
However his previous ones with info about tuning Holleys (How To Build Horsepower vol.1 &2) led me down some very long rabbit holes. Minimum estimated cost of those rabbit holes I'd say $400 and a few hundred hours.
You didn't think I learned so much about carbs by just reading books. Did ya? :poke:
I dont even want to think about the actual hours and costs.
