400 hp 5.2l vs 5.9l Magnums

I made the stroke the same but left the bore sizes at a huge difference on purpose but tightening them up with a 383-400 could yield get more discrepancies and seeming outlandish results.

Verification via a calculator also assumes much as variables in person builds or material and conditions of the quality of parts and machine work abound greatly.

To many variables to answer why I answered under perfect conditions and the gave a crazy variable in the most unlikely opposite direction aka worst case scenario.

In the above posts, his see- able claim is a 318 can out power a 360 through rpm. If I stop here, it’s a challenge for some to see that possible. But it is through changes of the engine. But he stated 400hp set of engines. And the 318 wins through gearing and rpm.

This is short sighted IMO since the 318 was helped in the conversation but not the 360. Might as well have given the 360 a 2bbl. & exhaust manifolds running 2.76 gears on 33’s.

Sound absurd? He does to me.

I've never once said the 318 would be faster at best I would be implying on par, To me there fairly close and setup right should be in a similar ballpark 1/4 mile wise. The other guy seem to glance at the 440 lbs-ft vs the 382 lbs-ft and concluded the 360 the winner without taking the rest of the driveline into account which was my point with the gearing that the 58 lbs-ft difference would at least shrink a fair bit with proper gearing . The 360 has a 10 ish hp advantage across at least part of the powerband don't know if that's enough to dominate every race.
