I'm not just looking at the peak, again here the under the curve if you lined up the peaks like you would if gearing properly. It basically the same if you don't agree you don't agree I don't what more I can show. Not saying this happens with every combo but you line up the curve there's gonna be less real gain or losses.
410 3000=250 3500=310 4000=365 4500=399 5000=420 5500=431hp
360 3300=252 3800=315 4300=360 4800=399 5300=418 5800=423hp
Cid, lbs-ft, 1st rear , torque to tires
410 480 2.45 x 3.73 = 4386 lbs-ft
360 444 2.44 x 3.91 = 4253 lbs-ft
