Some interesting info there. I would like to make a correction. The Engine Masters article i mentioned earlier was run with a sb chevy, not a mopar like i thought. Early oldtimers i guess. A 355 with 10:1 comp and 190 AFR heads. They tried lobe seps from 106 thru 114 with 108 making the most peak and avg numbers. The 106 and 110 were almost the same on peak and avg numbers. They were down only 4 avg hp and 6 max hp. Just an fyi.
