I think the 440 would be the easiest build. You could achieve 12,s and still run a relatively mild hydraulic cam and dual plane intake to keep street manners. No replacement for displacement.

A mild 440 will do that with no problem. I can't see going to a stroker to just turn 12's. Find a good used 440 for a decent price, good exhaust, maybe cam, and 12s will be easy.

how about a 360, use 273 rods, kb 10 to 1's, 508 hydraulic cam, adjustable rockers, windage tray, single plane intake, holley 750 with bigger jets and squirters. I had this in my 68 dart GTS with a 904, shiftkit, stock convertor, 3.91's. It would run 12.40's all day in 90+ degree heat. 32 degrees total timing. I had a full bodied car with full exhaust and street tires. Very simple to build, cost less than 2k in parts, and never lost 1 lb of oil pressure and I rode it very hard. It seen many 7k plus revs. Keep it simple and it will scream. Those stroker 408's are over rated and cost way to much for the power they make. Mine was well over 435 hp. Do the math. The best was 12.40 at 112mph. with zero traction and a 1.95 60 ft. time. With a stall and 4.30's and a small set of slicks it would have gone 11's all day.

Go as big as you possibly can to begin with. The 440 is the perfect platform to start from and with a VERY mild (read small cam, low compression) build it will go 12's with ease. On the other hand, if handling will be considered go with the 360.

A stock-stroke 440 will be able to turn easy 12s w/ no more than 3.55 gears. However, a small-block E-body will always handle better (more balanced overall) than a big-block version. I've owned both, so these are comments from first-hand experience. Figure out what's your priority and go from there. EDIT: A stroker small-block could be the best of both worlds.

The thing I like about a 406-408 SB vs 440 is less weight & easier to service. Also less fooling around with mounts, accessories, and possibly cooling. Pretty easy 12s, with enough torque that it doesn't need a bunch of gear. The 360 might be cheaper to build but will be a higher-strung setup for the same ET than a 406-408; but 12s are relatively easy. A 440 would require less modification for the same 12s. Either one would make a nice highway car, though the 406-408 will get better mileage, about 4-5MPG from my experience. The OD ratios are not an optimum "split" for drag racing, but building for torque would help there. There's no wrong answer, really, depending on how you want it to drive on the street, but I really liked my 406 Duster street car a lot.

Stroke the 360, eddy heads, 12’s….no problem…The best of both worlds, small block weight with big block torque.
67 Barracuda street car, 408, e85, 1.38 60', 6.44 @105.9 in the 1/8 mile, 10.19 @130.5 in the 1/4...so far....

Over square stroking with over +4" limits the rpm for max torque production. Even with a hot setup. A 4.12 stroke will shift around well around 4500,4800rpm. The awesome part is that strokers do not need a lot of gearing, the longer crank throw advantages the torque, in a similar manner as the mechanical advantage gearing. 3.08-3.23 gears are fine. It fits a road car up for highway driving and enough torque to pull stumps out. Not to mention, you , rapidly through the gears. Carb choice progressive go AVS 800cfm, or standard QJet.
The 440 engine is your best choice cause you say it is there, and the engine with the most potential for EASY power. Big Bore and stroke in a heavy duty package.
The 360 can do great things if build with in reason. For highest performance road driveability, the most recomendable way is the complete Edelbrock RPM 360 mopar package heads/cam/intake/headers/3.91's. It may get you to the actual 12's, but not much fun at 65mph.
