360 build ????s

So I have done a little reading. The best compression ratio offered for a 360 was in 72 with 8.8-1 running a 2 brrl. Otherwise 73-74 is 8.4-1. the websites I read this off of did not show anything for after 1974.

My question is what does a guy have to do to get the compression up?

As stated above it is a 70s era 360. Will be the stock rotating assemby. I have a set of J heads that have been ported and polished. (idk flow stats) They have .550 lift springs. I will be upgrading the cam. I like the purple shaft 284/484 but am still researching. Unless I come across a different intake I will be using my Torker II for now. I currently have a edelbrock 600 or 650 cfm. Idk if that will change yet.

Thanks for all the info so far!
