Looking for better fuel milage

... Something on the order of 218* intake and 230* exhaust with a 112 lobe separation maybe even 114 to keep the torque curve very wide. Would probably start about 1500 and not quit pullin until he got tired of it. Would pull over 6K. A milder cam, with 3.23 gears and a stock converter would BE faster than what is there now.....because it would rev quicker, have much more bottom end torque and be much less peaky in terms of the torque curve. The cylinder pressure with a milder camshaft would skyrocket resulting in much more power...

Been there, done that, absolutely true.
