340 cam in a 318

I don't have enough guts to try. For me it's a lot of work if it doesn't work good. Which 340 cam? I think I am going to bow out and just watch along. This would be a good You Tube series to do. A stock teen with a 2 barrel and put a 340 spec cam in it. See what it does.
I doubt I would do the 340 cam with a 2bbl with plans of leaving it a 2bbl. That's like polishing primer. I'd do just a 4bbl first and leave the stock 318 cam in before I did the reverse. Means the OP didn't state it, I'll give him the benefit of the doubt and say he'll be using a 4bbl.
