Are you tuning yourself?? You should easily make close to 1200 hp on 93 octane. That motor will handle a good 18 psi or so on pump gas. The power might not come on untill the higher rpm though due to the huge .96 AR housings.
If you ever have any tuning questions, I would love to help offer advice to turn that thing into a serious dyno queen!!
Those headers look sweet!!
