I'm with Little88 on this one. That stroker is going to handle more duration without getting unruly. The cam you have chosen is by no means large for that cube motor and I definitely agree that 430lbs of open pressure is excessive.
Depending on what your goals are: RPM, where you want the power, avg. HP etc. You should not have any issues making the numbers you quoted and even more if you use some different heads/larger cam.
