sounds like a good build. it will be tons of fun.
i don't think you will hit your 575-600 hp goal. i think around 540-550 hp with 520-540 tq.
as mentioned, 4500 rpm stall at the minimum. thinking more 4800-5200 rpm. don't worry about street driving it, i used a 5400 rpm on the street with my black R/T.
my first stroker i built was 410''. stage 3 eddie heads from Hughes. claimed 296 cfm but who knows. 9.5 comp, 615/621 lift solid cam, 254/260 dur @ .050 cam with 1.6 rockers, stage 2 ported super victor intake, pro systems 950 carb. 4800 rpm stall, 3.55 gears. car was 3880 lbs without me. it ran 12.05 @ 115 mph with to much convertor slip. i had 8% at the top end. with the right convertor, 11.60's was possible.
you have more compression, less weight which makes me think low 11's with you car.
