367 vs 410 Engines Masters

Icetech said

I don't understand this conversation.... the 410 makes more power everywhere up to around 5600? across the entire curve.. my motor will spend about 1% of it's life above 5600.. so you can have quite a bit more power across 95% of the curve for almost the same money? How is this 3 pages long? Honestly wondering what i'm missing...

That being said.. if i were making a motor that spent it's life in a specific RPM range like 5600-6000 i would go with the 360 and hope i never had to race the 410 from a stop :)

This 367 vs 410 ain't the clearest example, when comparing on the dyno graph people are generally comparing each hp at the same rpm, so at 3000 rpm engine A Xhp and B Yhp and yes practical at every point the 410 wins and if both install with same gear etc.. in car probably play out similar (410 wins).

But to me if comparing the true potential of each engine (what performance is possible) you need to compare at each hp point and see at what rpms engines A and B makes the same hp, cause if you were to run both for best performance you wouldn't be running same gear and stall etc..

So as we drive if you had 410 with 4.10 gears and I had the 367 with 4.36 (could be 3.23 vs 3.55 etc..) in 1st gear your gonna be revving 1250 rpm for every 10 mph and I'll be revving 1330 rpm for every 10. So if we both gonna 30 mph (at full throttle) you'd be turning 3750 rpm and I'd be turning 3990 rpm at 40 it would be 5000 rpm vs 5320 rpm so obviously were running at different rpms at any given mph so it don't matter what we both make at 3000 rpm, 4000 rpm etc.. but what hp were both putting to the ground at any moment.

Also notice the rpm gap gets wider as you go faster
