273 4bbl setup

I have thought about changing the cam, still on the fence. I'm looking for a modest gain, this car is light on its feet as it is, and still purrs like a true mopar. I'd like to keep that option open.
If anyone has a 3854S, I can rebuild it. Make me an offer, or I'll return/sell/trade the 3615S I have.
The best thing to do is open a wanted ad here. We all have a carb or two stuck on a shelf somewhere. You may find exactly what you need.
