carb recommendations
Holley ultra HP's are nice carbs. From what I hear, they are much better on fuel curve than the early hp style carbs. Not as fat off idle/cruise which is the biggest issue with the early HP's
I use those calculators as what's the smallest carb to run on an engine. Nothing smaller than a 750 on that engine, IMO.
Some recommend stuff that was generally accepted in the 1970-1980's. Now, things are a little different.
