Highest flowing sbm heads?

A 6.4 liter Gen 3 is only 390 cubes and how many cars have 5.7's under the hood. A modified 415 stroker should perform better than a 5.7 Gen 3 but it might be a stretch to run up against a modified 6.4. You might be the one getting your *** waxed.

I beat multiple Hellcats at Tulsa Dragway at the Mopar event a few years ago with that little 415", now we obviously have quite a bit more....but that weekend I ran a 10.48 @ 126....to date I have never been beaten by any modern Challenger or Charger....it can happen as there are some that are highly modified and run very hard but that's why I said 98% of them would be getting gapped.
