big block VS small block #1035415 07/19/11 01:03 AM 07/19/11 01:03 AM

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.

Would the 360 be allowed to weigh less? The fact is they do weigh significantly less and even if they are weighted to weigh the same you may be able to get the 360 to hook up better because you could put the extra weight over the rear wheels instead of over the front. On the other hand the 440 "should" have a broader flatter TQ band and recover better between gear changes, of course if they are both set up to take advantage of their own power band then 500 hp is 500 hp.

If both cars were set up ideally than the 360 would make up for the lack of TQ by turning a higher RPM multiplied by a lower rear gear ratio and TQ at the wheels would be the same "in theory".

For a 440 and 360 to make the exact same HP the 360 will have to rev higher (I suppose you could come up with a really crappy built 440 that had to rev to the moon to muster up 500 HP) but in reality a reasonbly well built 440 will not have to rev as high as a 360 to make the same HP. HP ir pretty relative to the air and fuel burned in an engine and a 440 will suck in enough air for 500 hp at a lower RPM than the 360 can. With out some for of artificial power adder the 360 needs to suck in the same air as a 440 for them both to arrive at 500 hp, no way around that and the only way it can suck the same volume of air is fill it more times in the same time span.

Do a poor job of transmission, gearing, or converter selection for either, the other will win. The drive axles don't give a hoot what logo is on the valve cover, or their shape.

How hard is that to figure out? A stock stroke 10:1 440 w/ ported iron/Alum heads, 520ish hydo cam, headers, intake and a decent carb will get you close to 500hp. You won't need a ton of stall because you won't have to spin the pee out of it to get it rolling or tall gears. Can that be done to a 360 and make 500hp...NO So if you are looking for 500hp and you have A. a 440 or B a 360 sitting on your shop floor which are you going to use? You seem to be Mr. Smallblock so tell me what it takes to make 500hp in one.
