5 degree total timing? Or initial?

You might need to go up a jet or 2 in the primary if its pinging with the same timing setting as before.

Initial, this is a mild 340 with J heads and small port Weiand 8007 Action Plus spreadbore. I haven't driven the car much in the last 10 years so I'm gonna run this gas out and do some tuning before I speculate too much. I will report back how it's running. I'd be surprised if it needed larger jets.
