You wont go wrong with Keith.

For street driving and I would say auto-cross too, I like a flat torque curve over the rpm range. Nothing more frustrating than mashing the throttle at 2000 rpm and getting a slow dog, at 3000 rpm getting pleasant power, and at 4000 rpm getting a tire shredding monster that you cannot control. Peaky engines can come on so sudden that they are difficult to drive. That said a few people like it and have no problems.

The other factor is what rpm do you cruise at the most? Well maybe what is the lowest rpm that you cruise at, would be a better question. You want the engine to be smoothed out before that rpm. It is a bit frustrating to have your engine wanting to buck and hop, when you are trying to cruise.

That said a choppy cam is music to my ears, but I want it to smooth out by 1800 rpm at the latest.

Hope one more opinion helps.
