Re: Changed my mind - now looking for a solid 240hp from 3.9. What cam?
Suffice to say I'm going to be leaning it out everywhere apart from WOT to minimize fuel stops. Quite common in the endurance racing to be pootling around at 25/35mph while the caution flag is out, so running as low as 16:1 AFR when the throttle is barely cracked open will be a great help.
