If you take the best factory 440 (sixpack) you should be able to get 500 with a cam and intake , rockers, headers.Throw in some cylinder head work too.. for laughs.

I can't see that happening with a 360. And if I'm right, there goes the budget deal. (which wasn't really in the original question)

right Rem... a SB will not make 500 easier or cheaper than a 440. 360 vs 440..... 440 WIN

That's not what the OP is asking. Even though I agree.

lol U R right. I'm not real smart, but wouldn't the engine that got to 500hp and max torque get to the stripe 1st?

Lets say you build a 440 and a 360 both stock stroke to make the same horse power (500hp). Do you agree the 440 will make more torque given the larger stroke? Do you think with properly matched gear and converter for the engines in say a 3000lb car will run the same ET? If they do run the same ET does this mean the smallblock would recover in between gear changes quicker to make up for being down on torque. I am trying to end an argument, so your thoughts please.

---

The 440 will have the larger more average power band over the 360. Hands down in the above senario it would be the winner.

Further, any mopar SB stroked bigger then 3.379 is a BB IMO

Wallace Racing - ET/MPH/HP Calculator Weight is as the car sits on the line: driver and gas in it.
Calculate ET and MPH from HP and Weight
Weight HP

Your ET / MPH computed from your vehicle weight of 3000 pounds and HP of 500 is 10.58 seconds and MPH of 126.58 MPH.

It doesn't ask if it is a 360 or 440.. Guess What.. It Doesn't Care..

I think that fat guys need big blocks and thin guys need small blocks, and when you put a fat guy in a small block you need a fatter wallet.... and that's all there is too it

who could have ever thought that BB vs. SB discussion could turn out worse than kids fighting for candy on the playground?

3100 barracuda with driver.been 6.84 et @98mph 1/8 mile/ with otb eheads/rpm air gap/750 carb/258*/268*@50 roller cam/kb pistons/10.0 compression/power glide trans.Bring the big block on with = parts and watch what happens.

I just pulled some time slips from june of 05 this was a very mild 440 build using the stock crank, stock rods,.030 over TRW pistons with 10.3 to 1 comp. with out of the box eddy heads and a mopar .590 solid flat tappet cam in a 69 valiant street car 3115 race weight set up for 1/4 went 6.739 @ 102.66 in 1/8. So there's a big block = parts so what would happen??

The glide slow the car down a tenth.plus a 750 carb setup lean 78/78 jets.Not to mention my .001 reaction time to your .100 bulb.I'll get thier first.

Luckily for the big block guys we are talking about straight line acleration here because if we talk road racing there is no way to make a turn with a boat anchor in the front

Makes sense. The big block makes it a muscle car. Muscle cars weren't meant to go road racing.

Ive seen 7600 out of a stock stroke 360 with mildy ported iron heads and a .484MP cam. Bash away.

I dont think my 440 will go that high (okay okay, I know it wont)

---

haha, Ive had stock big blocks higher Chris! BUT, your not making any power revving it that high...
