Default Custom Cam

I was thinking about experimenting w/ a custom grind and was wondering if there were any more specs to consider other than...

duration @ .050
duration @ .006
valve lift
LSA
Intake centerline

will this be sufficient info for the grinder and let them fill in the gaps or is there any other details to give them?

thanks, <img src="images/icons/smile.gif" border="0">

By no means am I a camshaft expert, but I do know there is a lot more to a cam lobe than the .006 and .050 duration number. Most of the time when you order a "custom" cam, you are actually just ordering your choice of existing lobe profiles, along with your choice of LSA and advance/retard ground into the cam.

IE, it's not as simple as saying you want a custom grind with xxx lift and xxx duration.

George, thats a good point you bring up. <img src="images/icons/smile.gif" border="0"> I'm going to call Izzo tomorrow and see just how much Comp lets you customize cams.

John, how did you select your cams before hand? Were they off the shelf grinds? or did you specify exactly what you wanted?

Chris, thanks for the links. That will probably keep my mind busy for a while. <img src="images/icons/grin.gif" border="0">

later,
Steve
