You should easily with that cam/heads & carb set-up, i was right around 500fwhp with stock 906s, XE284H cam, M1 & 750dp, the converter choice at 3000 won't be the best, thats what i would change, call PTC & have them put you in a 9.5" converter, mine flashed around 4400 but was still streetable, i see your going with a TR & 2 600s, thats what i ended up with at the end with my 451, don't let people tell you its not streetable, those TRs are great on the street when the carbs are dialed in, the idle quality was 2nd. too non compaired to a single carb set-up, i loved it, & the torque was un-real :toothy10: If you need any tuneing tips on those 1850s let me know.
