Nice man! I am in the works of doing a very similar build to you. I will be ordering a fab9 rear end, doulbe adj tq arm, adj lca's, adj phb, sfc's, and possibly some strange single adj front shocks and springs. I'll probably order all that in the next couple days. You can see my current mods and times in my sig. That 60' was cut on stock suspension, stock wheels with 245 nitto's. So with the the mods, the 4000 stall, and 3:90 gear I think you will easily pull 1.4x-1.5s
Are you going to be spraying off the line? If so you might be able to get down to higher 1.3's, if you can get the car to hook. Deff keep us updated though if you go to the track soon, car looks awsome man!
