The track rentals we run are more leinient with an 11.3 than a 10.3 lol. No ones done eagle heads on a 6.1 yet. The charger now has maybe 430 rwhp. NA with the 6.1 i think tuned well and set up properly i can get 11.1’s out of it and around 490 rwhp. I honestly just am not ready to run unlimited. I want to win each series championship if possible. Already took the 5.7 so, 6.1 is next.
