Who put the motor together?
What lobe separation is the cam and what is it the durations at .050 lifter opening and what ISA (intake lobe opening at .050 from TDC) is the cam installed at?
As far as the wide ban and the AFR Lamba numbers you may need to either fatten it up or lean it down to find out exactly what this new motor likes the most work scope up
BTW, did I mention Murphy loves messing with us hot rudders rant whiney whistling
