Engine combo advice

Wouldn't have posted and asked questions in a forum if I didn't want to hear opinions and facts. No apologies needed. The cam is bought and installed. I still need to break it in and get the tune up to par. I asked around when researching cams, but never did the acutal math for this particular one, (as I don't have the knowledge.) I was thinking I would end up high 7's to low 8's for dynamic. Was you resultant based on a computer program or based on experience? I wanted to be able to run 87 octane, to try to avoid the eye rolls at the pumps when the wife is with me. I also won't be using it on the track. Is a smaller carburetor warranted? The one thing stated that bothers me though, is the dcr at sea level. I live at 5200 feet... If you guys have a good cam idea for my combo, and I hope I have given enough information, please fire away. I won't be able to change it right now, but will give me options down the road when, "More" is wanted.
