You should be in the 11's is correct but there is alot of variables to what ET amd MPH you are running. Just knowing the HP is not enough to give an educated guess as to what MPH and ET you will be running.
I have 58" bars, stock converter for now, level 10 tranny, 16x10 rims with 16x10x28 Hooiser's.
Just had it dyno'd 557hp/589tq, air fuel 11.69. I asked JLP about the tq and he said it was where he started the pull from 3200rpm's instead of 2900-3000.
