AVS2 compared to Street Demon?

68 Coronet RT - I don't mean to sound snobbish. But with my spreadsheet that calculates EVERY SINGLE ROD AND JET COMBO available, which allows precise jetting data to be compared to all other available rod and jet data, which correlates extremely close to my readings on the AFR gauge, there is no better rod / jet primary or secondary jet size available that would make an improvement.

And watching the AFR gauge under all circumstances, the only way to improve this slight off idle stumble would be at the sacrifice of some other currently great driving aspect. As I've mentioned, I've got this tuning down to an art (at least for Edelbrock carbs). Under all circumstances (except this off idle stumble), the car drives flawlessly. Any change to my current jetting would yield poorer drivability. It is maxed out given the mechanical limitations of the rods and jets available.

It's so good in fact that if anyone here has a mildly warmed up LA 360, I would be happy to share my rod/jet main and secondary set up. You could try it and see if it doesn't make your overall street and WOT performance better. I'm counting on the switch to the annular boosters to clear up this lean stumble. I've read that it does just that.
