Thanks for the candid input. I will certainly look at replacing the cam.

All the cams that you suggested are marked as idle starting at 1500 through 5500 (roughly). What exactly does this mean?

One thing I do want to avoid is rough idle and/or having to raise the idle well over my present 800 RPM to keep the car running.

I do appreciate your input, especially since I know so little about the subject. But maybe it would help if I gave you a little more detail aboiut the car and what I hope to accomplish.

It is a '68 Camaro Convertible with a '68 327 motor - bored 40 over.
Has a Edelbrock Perfromer Intake(not RMP, not AIR Gap)
Automatic Transmission: 700r4 with a 2200 (or 2400 can't remember) stall
10 bolt Eaton Posi with 3.36 gears
Doug Thorley Tri-Y headers (1 5/8" primaries)
600 CFM Holley with vac secondaries
Electronic Ignition
Stock rad, stock waterpump
High output oil pump.

Will be changing stock heads - double hump 291 (with the smaller valves) to:

AFR - 916 (with 2.02 valves and lighter springs to match flat tappet cam, .550 max spring lift)
Airflow Research (AFR) 0916 - AFR 180cc SBC Eliminator Street Heads - Overview -

Scorpion 1.6 roller rockers

My objective is to maintain a well behaved, strictly "street" car that does NOT have an offensive idle. At the same time, I would like a litte more perfromance than I have today. (Specifically I am after some better low end torque and better off the line response.)
BTW I installed Hotchkis Frame connectors to stiffen the body.

With that in mind, would these still be the recommended cam?

Thanks again!
