572 RB Street motor advice?

We have a guy who runs a 3950lb+ Chally with all factory interior, not cut about with a very good sorted chassis, a 580 wedge with ported 572-13's, (close to 400cfm) a s/roller around 730", nothing too extreme and 11:1CR with 2 x Doms and makes around 890fwhp and runs 9.5's@141. At say 3200lbs all in and a good chassis you'll need a true on track 750fwhp to run 9.45@142 according to my numbers. As I mentioned prior, that 589 wedge my mate has bought is not quite there for you@10:1, a very small .620" s/roller, 572-13's probably ootb?, (you could do it with ported -1's) single 850DP@714hp, (that motor was built originally as a 605 with a 4.625 crank but it didn't work out for whatever reason), but that is easily upgraded for your needs, just some more info for you that may help in deciding which way to go on a more street orientated type big wedge.
