The lope at idle will all depend on the lobe seperation on your cam. The closer the seperation the more lope you will have. The lope actually robs horse power because of the valve over lap (both intake and exhaust open at the same time), but it does improve the scavenge effect in the cylinder. so if you can find a high lift cam with a 110*-114* lobe seperation you can build more power than with a 102*-108* seperation. good luck finding that with out having it custome ground.
hmm i dont agree with that, my engine has plenty of low end torque , LOTS of lope, and awesome power up to 5500 rpm
