Your math is out a bit. 418 does not = 360.

You guys are debateing about nothing that this thread has to do with just  The fact is 500 hp IS 500 hp weather it is a BB or SB if the car is tuned to hook perfect and keep the engine in it's own power band one will not be faster than the other. The SB will make less TQ but will end up with a lower gear ratio and TQ at the wheel will be the same. As for you guys and your peeing match, 500 hp is easy with either combo and costs about the same with either. A 1/2 decent port job on a X head or a 906 and similar priced cam intake headers carb... will make 500 hp. Machine work is the same and every component is going to be almost the same $$$. The SB will naturally turn more RPM to make the same HP but so what, matched with a 904 instead of a 727 the SB combo is going to be nearly 200lbs lighter. A 4 cylinder civic can make NA 500 hp and no TQ, they will just run super low gear ratios and turn the 500 hp into the same TQ as a 440 at the tires and the bottom line(the bottom of the tire) is what matters, it can still run as fast in a 3000# car but it just needs more gear to get the same TQ at the tire... of course a 500 hp honda is VERY much more expensive.

He said that he would go with a 340....340,.040 = 418"!!!!!

whats a 40 over 340?.. 345?
Mike you forgot the 4" crank that was never installed at the factory. 4" crank = not stock anymore.

Question one-yes
Question two- yes
question three - maybe?
For number three, it is all about the most efficient way to get the most average hp to the track the full length of it.
Odds are the small block will have a narrower power band than the BB, and will have more flash and stall. So, it kinda doesn't matter. You build the converter and pick the gear ratios to make the power band you have work.
When you say both making 500 hp, I assume you also mean they will average the same hp over a wide enough range so that they will be competitive.

so we now have 2 pages and 2 answers. so you all are say put steep gears in the small block to make up the difference in torque.but if you put all that gear in it to make up torque is it going to make it to the finish line in its power range?? to much gear and its going to slow down

500 hp is 500 hp. if both cars are optimized, the small block car will go faster (less weight). the two engines will have different torque curves, because it will take a bigger and/or better head and cam for the 360 to make that number, not because of shorter stroke. torque is a factor of cubic inches more than anything else. the 360 won't need to make (and won't make) as much torque to make 500 hp, because it will be higher up in the rpm range. the cars being optimized will level the playing field. that's where the weight advantage will win the game for the small block, imo.
they weigh the same

I was going to say that, but was wondering if he ment reciprocating weight
