CAPRI306, it's interesting that you say that. When I had my engine rebuilt, I put an E cam in it, and it works great, and it's a stick, and the rest of the engine isn't quite stock either. The shop that did the work said that they have build several engines with that cam with good sucess. But I agree with your assesment of the power range. I believe my car pulls just like a stock mustang up to about 2500 RPM, but over that, it really pulls hard.
When I bought the cam, basically I needed one that would be emissions legal. The E cam is, the B cam is not. Not that that's a big worry to most of you.
But to answer the questions, yes, the B cam is more radical than the E cam. But both are a definate improvement over stock.
