Remember a lot of it is gearing, too. With my 3.54 rear, 295/50/15 tires and that wonderful .64OD gear, I hit 150 at 4300RPM.
With my solid, flat tappet cam I don't red line to a good 7000RPM, which of course, translates to over 240MPh. I think she might do an honest 165, maybe a hair more, but maybe not.
