Cam Duration Vs. Usable/Used RPM Range

moper said
I have some other questions back at you...
What info is Crower using to determine those power ranges?
Do you feel that the time to determine the cam is after the rest of the package is put together?
What determines the "minimum amount of duration to achieve a rpm shift or redline"?

I think I know what you're asking - but the way you're asking it doesn't make much sense to me... if that makes sense...lol.

I have a hard some getting thoughts onto paper, always have.

Basically the smaller cam would probably be the best "all around" cam because it would come in sooner, and not go past intended usage BUT if your rpm range was high enough and you are running a high stall (4500, relative I know) why not run a cam that would build more power in the mid to upper being its never going to see the low.

is that at all better?

Which ever one makes the most power in the rpm range that you're running. That would be the faster one....providing everything else is the same.

Well right, and in reality I guess that's what it all boils down to. The smaller cam would make more power at a lower rpm but the bigger cam might make the same power or better in the "usable" or intended range.
