47 degrees initial time? help!!!

Generally in LAs you'll fall between 32-36. Maybe a little more or less. Less means you're getting great flame travel. More means you might wanna see if you can improve your spark. Make sure you're not running rich either. Or it will want more timing.

You always want as much initial as it can take. Keep turning up the initial until it starts to give you trouble on hot starts (kicking against the starter and such). Then back it down a couple degrees. Then shoot for your total. And adjust that based on where it makes most power. And as always listen for pinging/detonation. Sounds like you're on your way there!
