The Edelbrock Performer cam is just an old school generis grind. It is exactly the same as the Summit #1102 cam, and the Summit cam is less $$.
If you want a little bit of a lope, you might look into the Comp Cams High Energy cams. In my expereince with them, they have a little lope at idle. Something like this one.

When installing a flat tappet cam these days, you must be very careful and dilligent about following the proper cam breakin precisely, and running a flat tappet cam friendly oil thereafter. If you do not, more than likely the cam will go flat, and all of that metal will be thru out your engine. There is a thread in the 'Engine and Drivetrain' FAQ about flat tapped cam compatable oils. Definitely worth the read......if you weren't already aware.
