Taking any issues of sleeving out of the equation. An all-bore will dominate a stroker in every way of similar displacement.
All bore has the bennefit of unshrouding the valves, for better flow.
Less side wall and recipricating loads
Quick revver
Great option for forced induction.
With a stroker you get "dead spots" and top, and bottom dead center while the crank is moving, relative to an all bore.

Bottom line is bore over stroke, when displacement is similar, the bored motor will dominate in a drag race.

I tend to think like this:
A4
Lot's of low end torque fun to drive around town a 382 stroker would be the most fun.
M6
Fun to drive and rev a 382 Big Bore would be the most fun.
Easier to live with and least likely to have problems with: 382 stroker

Yes, a stroker will probably make more torque, but all bore uses less piston speed which long term is better. Like I said before, them hill billys, (NASCAR) use big bore small stroke. They get 750 hp out of a 356 ci engine. That is 2.1 HP per CI. That my fine furry friends is phonominal!!!!!!! A stock LS1 is probably right at 1.1 HP per CI. Cons with a big bore is it takes the flame front longer to go across the piston. If you want that big block feel, go with a stroker. If you like hangin em high, big bore will do it. But what do I know,(built a 525 HP RB Mopar at the tender age of 20 years not even using the best parts). <img border="0" alt="[devil]" title="" src="graemlins/gr_devil.gif" />

everything else equal:
500 RWHP 460 RWTQ
460 RWHP 500 RWTQ
FaSS Blac,
A NASCAR motor is also a pile of junk after a race and they idle horrible, not a good comparison to the street cars we got goin on.
Same with a 950 HP CART motor, there amazing but totally useless on the street. Not to mention methane gas.

The engine doesn't know whether it has more bore or stroke. The heads and the intake ports are what makes power. They only "see" pressure drop. There is no difference between the two according to the heads except that the motor with more bore can "breathe" better due to either larger valves and ports or the same but less shrouded identical ports so the "bore" motor will ultimately make more power. As some of you other guys noted however the bore AND stroke motor will make even more than the others.
