440 build, I need some input

We used to run 11.60's in a 3950# (w/ driver) 71 Road Runner w/ a 440 6pk. It was a stock eliminator car, but the engine wasn't anything really trick. (The faster cars in D/SA, our class, run low 11's, some hi 10's) 11.60's in a 3950# car comes out to about 500 hp. (Use any online calculator.) With 500 hp and 3000#, you should be able to run hi 10's. I don't know if your parts will make 500 hp, maybe others can estimate. It's not hard to make 500 hp w/ a 440.
Those tires are too big. You have to drag those things all the way down the track.
If you have to buy a convertor, get the right one for your combo.
