One thing that is almost always left out of these conversations is the torque curve. Another argument that comes down to do you want a slip to say my engine made xxx horsepower or do you want an et slip that shows how well the engine makes power over a broad range and is utilized.

no matter the argument no substitue for cubic inch. no matter what u do to the smallblock if you do the same mod to the big block the big block will make more power

ok put a turbo on a 360 that makes 500 horsepower and 440 that makes 500 horsepower same difference i will play your silly game

and if this is correct i could get a srt4 motor make it 500 horsepower put it in a 3200 lb race car and spank all the small blocks and big blocks

231/237 cam in that 408 and 480ish HP ??? sounds more like maybe a 430hp engine

Hopefully, all the engine builders who deal in max N/A engines are keeping tabs of this thread. All these years of trying to shift power UP was an excersize in futility. They should have been trying to increase TQ at 3000rpm.

Who knew that all they were doing was abusing the valve springs.

Perhaps this will signal the wave of the future......turbo diesels in Pro Stock, with 1000tq @ 1800rpm and 300hp @ 1801rpm.

The diesel analogy took the cake.

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

---

Bad humor on YOUR part. Why bring up cows crapping all over a person when it was a metaphoric statement about engines. At least, that how I put it as. The cow chip issue, I was trying to be funny, on that note alone.

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 thuoghts please.

---

First, never said anything against power adders.
Second, stock strokes, NO stroker combos

Yes, they would run close in times.
Yes, A smallblock would recover a bit quicker (depending on equipment). Again, depending on eeqipment and tune, top end hp rules, (shorter strokes) if torque peaks late in the midrange.
However, a high but nearly flat torque peak in the lower midrange, (longer strokes) can be equally as strong. There is another factor in trying to measure an engines performance potential. Rod/stroke ratio. Although NOT 100% accurate, but it gives an indicator of the engines basic potential for performance, (equipment being not part of equation). 340's, for example, have a 1.84 ratio - which lends them nicely to higher rpm power.
360's on the other hand, have a 1.71 - which gives them a GREAT advantage as a midrange high hp/high torque motor. SOLID base for a stroker or "standard arm" HOT street/strip.
440's have a 1.80 - which is nearly equal in performance as the 360, but with a slightly BETTER potential for higher rpm hp.
Not to say 360's can't rpm up but it also about the equipment (parts) which makes it all happen. Given both at the 500hp level, again, they would be nearly equal. A point about the 360's rev drop, it would NOT be the same as a 340's, unfortunately! It would be at slightly lower rpm than the 340's, characteristic to the 440's (again, equipment depending!). If the 440 has a balanced bobweight LESS than the 360's, it's a wrap!! But it's not needed for a 440 at the 500hp level. 500hp 440 engine builds are standard "street-level" combos, they are unnecessary, unless you WANT TO spent a bit more money on
the parts/balance job just to "maximize" that particular combo at THAT level!! At 550-600hp or MORE, IT IS absolutely beneficial!! It would be routine for the 360 (at 500hp) since the nature of smallblocks are to rpm quicker/higher than their big block counterparts. And you would want maximum hi-rpm reliablity from your smallblock!! Anytime you can REDUCE reciprocating weight, you are adding rpm and possibly more torque.
