I would guess around 225-235 rwhp. Bolt-ons only get you so far as the big power gains are made with heads, cams, and intake. Other options are Nitrous, supercharger, or turbo charger. I have every bolt-on there is including heads cams and intake and put out 300 rwhp with my N/A motor. On nitrous it did 432 rwhp and 553 ft/lbs torque.
