Chaplin,

I think you are at a point, where its all "relative" to what is rough or what is calm is to you. Bill told me the same thing, and I ended going a step up from his 247/252 cam, and I love it. I would suggest you hook up with a few people with FEs, to see, hear, and feel the engines run through a full exhaust. What you might think is rough, others might consider tame... For me, a tame or flat sounding motor/cam in a Cobra gets a bit boring after a while, but you may be planning on driving your car a lot more than I do, etc. I've ran in to a few gents with FEs in their Cobras, that have stepped up vs. stepped down on cams with the 2nd or 3rd+ FE, by going too conservative the first time. Whatever you do, take the time to find and select the cam (and valvetrain components, rockers/etc) thats right for you and the application that makes sense for you. Here is another place to check for a 5th opinion..., try: Tom Lucas at FE Specialties 916-339-0427. Tell him I sent you. Good Luck.
