4.10s with a 31" tall tire. It has on paper a 8.9:1 compression ratio and a small 220/220 @ .050 cam with .478 lift and a 108 LSA. Heads are bone stock Magnums and the engine is .040 over. Edelbrock Performer RPM air gap intake and a 1" carb spacer. It has light spark knock under moderate load on 87 pump swill. I've knocked the timing back to 28° total at 2700. I don't want to go any farther.
with that gearing and aerodynamics that MPG is not out of line,
especially if parts of trips are off road and on hilly country roads
sometime in the future use an oxygen sensor to find out your “ballpark” air to fuel ratio at level highway cruise
