For a street car, if you can find a cam that will give excellent average power and great peak power both, then you've stumbled onto something. Overlap is of course important because you don't want reversion, and on a lower rpm engine where the exhaust can't scavenge the intake efficiently, it makes things twice as bad.

I've found that a tighter split with advanced cam timing really increases throttle response as well as gets rid of some of that lower rpm inefficiency.

What's the advertised durations on the cam that you have ordered?
