A stock stroke 440 w/ some Trick Flow 240s and a decent cam will get you mid 11s easily. You just need to know what you have currently (decent crank and rods, etc.) and do the homework to compare what it'll cost to rebuild what you have versus building a stroker. The stroker is great, but will add a bunch of money to the project. A decent carb is way cheaper than going EFI. Reading things nowadays it's amazing these cars ever ran at all w/ carburetors on them, lol.

For what you're wanting, a stock crank, stock LY rods w/ some ARP bolts, and some $450 Wiseco Pro True Street pistons will work just fine. I'd get Dwayne to spec you a cam...but even a shelf hydraulic flat tappet (something comparable to the old MP 509/292) will work. Some Trick Flow 240s, a decent single plane manifold, 850 holley, etc.

Not knocking anyone's recommendations thus far, but mid 11s can be done cheap. You'll have $2500+ in just the stroker kit (if buying new parts). You should be able to do a stock style rotating assembly w/ a freshly turned stock crank, resized stock rods, and new pistons for $1k or so.
