The 4.11's prolly won't help much cuz tbi's power band is kinda low, the 9" eats a little more power too. The locker is kinda old school, but thats all gravy. Without knowing injector size, valve size, cam lift, rocker ratio, stall speed, tranny, exhaust setup...it's pretty hard to say. You might get there...but without knowin more, I'd have to say no.
I'm assuming your setting the car up for a real engine and that your not planning on keeping the TBI, otherwise your setup would be overkill. And the sig...(edit)it's fixed

you didn't say anything about the head gasket thickness or milling the heads, so i'm gonna assume you used a steel gasket and didn't mill the heads, and also assume you installed the cam straight up, and that you've got headers, and that your car is around 3500lbs, and that the throttle body and injectors are 670cfm 2bbl....and give you the benefit of the doubt and figure you ended up with around 8.5 cr because you didn't mill the heads (assuming they're off a 350 like everything else) and stock cr was 9.3 with the lil heads. And I'll say you'll run high 13's with the engine screaming across the line in 3rd (still assuming you have the 700r4) with the engine making around 300 at the fly and 270 at the wheels.....but alot of this is assumption, and "assumption is the mother of all **** ups"....I can't emphasize that enough, there are alot of tbi guys on here that have alot of money in their setups, and they still find it hard to be competative(there are always exceptions).
I'd say get rid of the tbi setup however you can, get the compression ratio up, and either stick some 28's on the back or get a more street friendly gear....and uh...if your planning on having the car hook at all, save up for a tranny
