Took the first all highway trip with the new engine tonight. Drove to Athens to meet the girlfriend for dinner. About 80 miles there and 80 miles back. Plus driving while we were there.

Averaged right at 16 MPG. If I had cut out some of the fast passing and about 20 minutes of idle time I think I could have gotten better. Not bad for a truck with 33s, stock gears and 4 way unbalanced tires:thumbup

Yup, new longblock. MSD tuneup, timing at 13* and the headers and exhaust. Running Mobil1. Everything else is stock.
