It is funny all this talk of 45yo ancient big and small block engines when these modern cars with tiny cid engines like the Boss 302 can kick ass to the tune of 11.70 stock with just drag radials
Umm... I do think Chryler made the slant six motor. Has two LESS cylinders than YOUR Boss 302. They're ALSO ancient, (in YOUR words). Would you run it against this 45-46 year (young) old ancient engine? I doubt it!!

I don't have a 2012 Boss, but i bet with some bolt on's and a pc upgrade it would run with it, then kick that /6 in braking, and on a road course, all with the a/c and stereo cranking with better mileage to boot, .

I think I would rather LEAVE the radio and A/C out, if I had one, driving on the "track". Can't do nothing about the heat in the helmet and suit. Besides, I would want to be "focused" on the track and car's handling condition, rather than the radio. I don't like spinning out and ending up hitting haybales or tire walls, even worse guardrails!!

It's amazing that in 2011, people still don't understand important things, like "shift recovery" and "useable rpm".
It has nothing to do with....."my big block is better than your small block, or vice versa.
Pity, I tell ya.
There are no given right or wrong answers here, just opinions and facts. Both can be useful to learn from.
Yes, there are opinions and facts in this thread.

Good grief! I can't believe the "bitchiness" of some of the small block guys in this forum. Small blocks are great, I had a worked 360 in my car for a few years in the late eighties; but the i went big-block. Wow! what a difference! And that was with much the same sort of combination as the 360. For a very hard-driven street car(& i'm talking 70-135 mph)they would jail me today,i guess)the small-block just couln't compete. I used the 440 for 18 yrs & then i went with a 440 Source Stroker. Oh boy! The smile just couldn't be taken off my face. Cubes equals Torque,& that rules. With 2:75 gears & New-Process I do 12:00-12:25@ 117-118mph with a 4000 lb Charger. As for Turbo's. Great! Thats probably what i'll play with next. But isn't that just artificially making a small-block think its a big-block. Kinda kills the argument some of the replys have used. The stroker has all the parts except for crank,rods & pistons. It gained one full sec: & 4-5 mph through the 1/4,& gained 5-6 mpg imperial. Better volumetric efficiency I guess as the shorter rod ratio along with bigger cubes reading all parts as being smaller than what the 440 see's. Mike in New Zealand My

Just one more thing too. A sensible combination of parts at an affordable price, 7000 revs is a sensible ceiling for both big & small blocks for an everyday street car. My 440 with TRW 2355 six-pac pistons on just polished & shot-peened rods did 10,-Yes! Ten years before it needed a tear-down. Nearly 180'000 miles. And I used to do about 50 1/4 mile drags a year using street tires so that i could sit on 6700-7000 doing wild full-lock to full-lock power slides. Wasn't fast, but who cares,the crowd loved it & so did I. Thats why Fuel Altered's wer a crowd favourite in their day. In this country there is a huge following of American Muscle Cars doing cercuit racing as well. Crowds of 10,000 easy,& for a country of 4'500'000 people, thats big. We even have Mopar National Drags,& over 100 Cars arrive. Awesome! Mike

I agree the big block torque curve will be broader, but I said with gear and converter to match the combo's.
With that said a big block with a 275/60/15 tire with 3.23 shifted at 6000 rpm would fall back to 3500 in second, then back to 6000 and fall back to 4000 in drive. While a small block with the same tire and with 4.10 shifted at 7500 would fall back to 4500 in second and back to 7500 then fall to 5200 in drive. That small block would have 500rpm more pull in 1st-2nd shift and 300rpm more pull in 2nd-drive thats 800 rpm more total. This is figured on both cars with a 727 and stock gear ratio's. This would also be with the converter dead locked which we know don't happen, but still more useable rpm from the small block.
You stated matched optimized combos between the two. A 500 HP BB is not optimized with a 3.23 gear. Further, it wouldnt fall back to 3500 rpm in second with the right vert.
The original question, 500 HP BB 440 vs 500 HP SB 360 in a 3000# car. In this case alone, at this level of performance, the broader torque range of the BB,s extra stroke should win.
The argument of Mechanical advantage with more gear has merit. But you can overgear IMO, Ive found that with my 500HP combo, it likes to dwell a little in first gear with the verts torque multiplications aspects.
Ive tested 3 gears with the same HP. RPM and gear multiplication isnt always the fastest way to the stripe at these 500 hp levels.
Pro stocks 500CI and 10,000 rpm,s sure different story.
