340 Vs 360

Sure, it makes sense! See, they are say'n all being equal (same carb, cam, etc), the bigger displacement makes more torque. But if the smaller displacement has the same carb, then it has more because the cubic inches per cfm isn't the same. But if you give the cfm's according to displacement, then all isn't equal because the bigger engine has a bigger carb meaning more opportunity.... Seeeeeeeeee?????????????????

I see what your saying cfm per cubic inch is different if built with the same top end the 360 will make more torque but 340 will turn more rpm thats why they equal out. Because what I like to call dynamic cubic inch a 340/360 are there static engine sizes (non running) but a running 360 turning 6500 rpm would have a dynamic CID of 360 x 6500/2 = 1, 170, 000 cubic inches per minute and a 340 would have to turn 6882 rpm to equal out
(1, 170,000 x 2 / 340 = 6882) and a 318 would have turn 7350 rpm. Rpm is basically another way to add displacement to you engine.
