Usually if a manufacturer is designing a small capacity engine with multiple cylinders (e.g. 6 vs 4) they are looking for a revy motor so will give it short stroke rather than a smaller bore. You really need to look at it on a cylinder by cylinder basis. What is the ratio between bore and stroke. Compare a 302 Chev to a 350. the shorter stroke (3in to 3.48?in stroke) allows the engine to rev higher but make less torque. Same goes for 3k versus 4k, 3k is much revier. Best way to compare is to look at same capacity engines with different bore/stroke ratios and see how they compare with the same number of pistons. The 3S-GE / 1G-GE is an interesting comparison but will be distorted by what the manufacturer wanted from the engine. Hp is also only a measure of torque vs revs so is probably best to talk about where in the rev range the torque is made. The same (or even a little less) torque made 2000 rpm higher will give you a higher hp reading. Just my ramblings. Callum [Report message to a moderator]
