going fast help
Good answers above. The key is to balance budget vs performance. Obviously, the faster you want to go, the more it will cost you. With XE274, 750 carb, KB pistons, the potential is there to run 13's. That's between 13-14 sec, which is a wide margin. It's possible to go faster. It may cost you more than your $1,000 budget. There's a few members that run into 12's with that combo. But they've invested time in the details as well as the package, jetting, launch technique, tire pressure, etc. It's not a simple formula. I'm still learning this myself.
The answer to your question is subjective.
For me, my Mopars are not my daily drivers. I can build without having to worry about streetability. My limitation is budget.
Like Rumble said, the Mopar engines and/or chassis books lists combinations for each bracket you want to run. Those combinations are a starting point. You sould still need to do the tuning, etc.
The simple answer is this, 1) stock, or close to stock, rebuild for now and be done with it. 2) save a little more (if you can prolong your rebuild) and do the things that the members suggest in your other threads.
But you should decide what you want and stick to it.
