With the above setup, it will yield 30 degrees of advance at idle, that sounds very high. I have not tried it yet, just seems very high.

I have bought the Crane kit and installed it, but have not run the engine yet.(I just discovered my NEW China-Ebay HEI's vacuum advance canister diaphram was broken).
At idle my trucks motor runs 34 degrees! Runs like a top, and trust me, I"ve had many people saying, I cannot beleive that things running with that much degrees at idle lol. Who knows, but mine runs fine.
