Whatever feels good, around 900 or so. Maybe a little more if it has AC. Just my opinion.

Mine idles at about 800rpm.
It is mostly stock on the inside as far as I know.
The rebuild paper work states "RV" cam, but who knows what that really is.

Thanks for your input

Mines an '85 with HD emissions, but its the same for Manual or auto. I have a Sanden compressor with the rest of the A/C being OEM. I don't see too much of a drag on the engine when the A/C is on. The 454 doesn't have the A/C idle kicker like my 350 truck did.

I keep mine about 750 to 800. I like it a little lower to hear the cam better. Lol

Auto with no ac too. Rv cam too so really don't know what exactly. Was on there when I bought it.
