416 4l60eHolley single plane1050 atm3.42 gears.235 m/t et street ss Part throttle just past 60ft. Averaged 60% throttle until 1.5 sec in run according to holley datalogger. Which resulted in it shifting into 2nd at 6200 rpm instead of 7000. It has alot more left in it as the intake is still .075 larger than the head port. Also the afr was reading in the 13.6 range most of the pass

Here is a screen shot with the holley showing part throttle til 60ft. Not sure how much is to be gained here vs being able to floor it right off the line? Im guessing .05 to .1 improvement at just the 60ft.
