What's it gonna take?

I've got a 340 with forged 13:1 pistons, an 8 bolt billet crank, and I'd like to put it together and in some A body in the family. I've got a good 727 with a manual valve body and a 10" 3500 stall, we have some 4.56 gears also. the car will have a tied up fram, mini tubbed, stock tank and a Holley blue pump. I have a set of X heads I can port and a holley strip dominator intake and a 750DP HP carb. What will it take to get this into some mid or low 11's ? I need to pick a cam that will be okay with my converter, preferably a flat tappet probably solid. So what do I need to do or is this off to a good start for an 11 sec car? Thanks much
