Holley guru's- need advice

I meant nothing by what I said,I love to learn too.Trial and error is how I got my education,it's was costly.It's just that a good holley kit around here is $100.00 or so,or more if you want a trick kit.And a modified main body can mean trouble without an O2 and reading plugs(or dyno time) to see what the fuel curve is doing.Lean is mean.I have friend that thought he was a carb guy and melted a 440 from not knowing.I just thought with what you were asking it would save time, money and headaches for you to just get different/new.
