So using some of you guy's theory any engine 500 hp no matter what the torque "say one is 500 the other 700" they will run the same if every other aspect of the combination is optimized? not trying to argue just trying to understand.
Yes this is right torque is equallized through the rear gear. Say 3.91 for the big block and 4.88 for small block (as an example)

They BOTH have to make 500 HP AND weigh 3000 lbs.
Looks like the original poster isn't going to settle any argument and started one here.
I'm going to throw a cow chip in this thread and leave it alone, before !! How come so many GOOD POINTS were produced in THIS thread, and not too many on the "383 vs. 440" thread? Hmm, basically the concept is the SAME, with the EXCEPTION of the vehicle weight.
Humm...... Cow Chip..... ..... How high do you turn your cow ....... .......
As high as it can go, without it letting loose all over you.
Ya ask a simple question and seems that cows just want to crap all over ya This post needs a little injection of bad humor every now & then

i am glad i read this now i am going to tear out my 488 inch v-10 and put in a stock 340 they both make around 300 hp so there will be no difference. i am liking the small blocks

Not a bad idea. Come to think of it I wasted the money on my cummins should have just got the 360 same hp, just a gear change from same performance.

It's not a Mopar comparison but it is somewhat relevent to the arguement. I think it was Hot Rod a few years back that built two engines, a small block 406 and a big block 406, same cam profile. I cant remember the Dyno numbers but the big block heads flowed better so it kicked butt on the small block. They both went in the same Chevelle with the weight the only difference, the smallblock managed 12.50's I think and the big block ran 12.30's or 12.20's, even with the weight disadvantage and the same cubes.
The only reason the big block won was because the gear and converter favored it. You cant use the same gear and converter becuase the big block made more torque.
472HEMI you might as well pull the v-10 and put in a 340 because when you don't get the truck out of the garage it doesn't really matter. They both will rust away to nothing at the same rate.

Which one will last longer at the 500hp level? My vote goes to the BB.
Mopar to the bone!!!

Your Whole argument is correct on paper.
But it isnt in reality. The 500 Hp SB power curve will be smaller then the BB.
Unless both combos are pegged at the start to finish at 500 HP, witch they wont be. The BB with the wider torque/hp curve will be the winner.
Your argument is a theoretical math/physics argument on paper , not a reality argument.
500 + 500 = 1000 on paper.
500 hp BB and 500 hp SB doesnt = the same ET with different torque curves!
Further, in reguards to HP, math and physics being so precise.
Why is it that every stinking website for mph vs weight = xxx amount of HP is so far off from one another by 100 HP or so.
HP is a Calculated number based off of RPM. Both Torque and HP are for real. Torque can be measured, but HP is calculated.
And it can be calculated pretty accurately, But not on a vehical that races down a track with a variable Torque Band width.
For the arguments sake Im on the side of the BB is the winner in this same 500HP senario. Because in reality, the two combos will never be fully optimized to the 500HP

I was just wondering what made the fastest pass at the heads up shoot out they just had on here. Was it a small block or big block?
