Shake out advice

[csw]

Have enjoyed driving our "new" backdraft the last three weeks and answering the usual questions along with spreading the word on our cars. Have put about half the number of miles the previous owner put on it in 4 years and the kids and wife have enjoyed it just as much as me. Got 2 questions that surely someone has run across:
1. The drivers exhaust is coming out "wet" while the passenger side is dry. We have a 392 crate with 1100 miles. Getting smoke out of the same pipe even after it is warmed up and plan on dropping it off Monday. Mechanic wants to adjust carb (670 street avenger) first before doing a leak down test.
2. Brake light on passenger side comes on when turning on lights.

Thanks in advance for sharing your knowledge as I'm sure someone has experienced these shake out pains.
