why a custom built converter isn't for everyone....

you do realize, I'm sure, that nobody knows the absolute correct answer. Call 2 of the best cam grinders (or converter companies) you know and give the same info. Don't tell them that you called both of them. Let them both grind you cam (or build you a converter), and I don't think every characteristic of the will be the same. Even though both "work", which one is wrong? Or is there two right answers.... ???
Id be willing to say call the same company twice and on different days and you would get different answers.
