Cam choice for low compression motorhome 440

I'd suggest something cut on a 106-108 LSA and install it at 100 or so.

You want to get the dynamic compression UP and installing it ahead will get that done. Similar to what the whiplash and comp thmper cams do.

Ignition timing, primarily initial will play a BIG role in how the car performs at idle and just off.
This is what I expected to hear, the tight LSA will also help the fact that we live at 3000ft elevation here. Thanks for the input, since it is a friends ride I don't want to make a bad choice for him.
