The more cubes, the better. If you are going to do a stroker assembly, might as well go 7.10 H beam rods, 4.5 stroke. A light dished piston, ported small port aluminum heads, and a roller cam spec'd somewhere around 260 @ .050 on the intake will make for one mean street strip car. there are guys on here much better able to comment on the final cam combo, I am sure some will chime in. The limiting factor here will be the 6pak, so the extra cubes should help more than usual.
final result should be a motor you can shift at 5800 or so and will have gobs of torque from 3000 rpm up. I would also consider some aluminum main caps, and shoot for a light rotating assembly to help with block life.

I just put a new 520 in my Road Runner for Drag Week this year: 4.375 crank, .030 over stock block, prepped with ARP main studs, 7.1 rods, .990 pin, 11.3 to one CR, ported "stealth" heads (by MCH), RAS 1.6 ratio rockers, MP.590 solid, 1/2" hemi pickup and hemi pan, stock valve covers (with some work to clear the rockers and hold down studs), 2" Super Comp headers, street dominator intake, HP950 carb. The engine is painted and other than the headers and the intake, it looks pretty stock (the intake doesn't even look that far off, I ground off the Holley markings on the front before painting). Drove it from Indiana to Kansas, ran Drag Week through Kansas, Oklahoma, Texas, and back to Kansas and then drove it home back to Indiana. Changed the oil once and checked the lash twice. Best ET: 11.36 at 120.2 , pig rich, with wheel spin at @ 3900# with me in it. Best MPH was 121.1 at @ 3850# with a soft launch (11.53ET) while I was getting a feel for the new setup.
I agree, go for max cubes, but for appearances you'll be limited to the stock block and probably a 4.375 crank unless you go external on the oil pickup. With better traction and a little lighter you should be a bit deeper into the low 11's and it is pretty reliable. You might want to consider having MCH rework the intake when they do the heads, you'll need the CFM with an engine this big. I think my engine might benefit from a bigger carb, and I could swap cams around some, but it works pretty good and is very streetable as is.

My car should run 11.teens. .030 over 440 ross pistons (11.2:1) H-Beam rods, comp cams solid roller 588 cam, H/S 1.5 rockers, Ported stage VI heads, FACTORY 6-pack, Snow perf meth/h2o injection kit, tiny 1 3/4 headers, 3" exhaust, 3800 Turbo Action stall, 3.91's in an all steel 70 charger..except the glass "chevy" hood. Going to shoot for 10.9999 next year with 2" headers, more agressive tune, harder driving and traction bars.

 And maybe slick shift or face plate the trans. Clean power shifts are a must to be quick. And 6pacs with vac pots gotta be w.o.t. the whole time.

My 70 road runner with a stock bore 440 11.5 compression,H beam rod edelbrock rpms out of the box,557 mopar cam,Crane gold 1.6 rockers,and a 6bbl.A 5000 stall converter,and 4.10 gears.At a weight with me in the car of 3895,has run a best of 11.53@117,on a 10.5 slick. Don't forget that at 11.49 you have to have a roll bar.

It should be easy. We run a NSS 65 Belvedere with only 446" 9.9 to1 comp,906 heads,edelbrock 2x4 intake,2 edelbrock 500cfm carbs(junk) would run faster with a single carb intake,4.10 gears,28" tire,8" PTC converter,3600+lbs 6.80's@100mph1/8 mile. Recently swapped the Comp street roller for an Ultradyne(Tim @ Bullet cams) and picked up .2 and 3 mph while keeping the idle nice. Good heads and more cubes should make it easy.

VERY cool! 11.30's and hundreds of highway miles...gotta love it!
I'l like to know about the rest of the combo: Trans, converter, gears if you don't mind.
Not to mention: PICS ! ! !
