Question for engine builders

[WheelchairWarrior]

When running a 2Bbl engine, what change should you make in the cam. I guess the question I have is... Our engine rules call for 2 Bbl carbs, however the cam rule is unlimited. If I a have cam that worked great with my 4 Bbl gas carb, how would that cam work with a 2Bbl gas carb?

Is it an untouched or gauge legal carb rule? Generally alittle less dur, overall with alittle less exh then intake dur. As with any engine, but more rocker ratio is a pretty good gain.

The carb will be checked by a drop in, go/no go gauge. The carb will not be removed to tech.
