360 stroker how much HP is picked up if everything else stays the same?

I could not find the engine masters ep. 18 where they compare a stock vs stroked engine set with a Chrysler 360 vs a 408.

Both engines were bored over @.040, both had Edelbrock heads and intake, carb size was the same, an 850 XP Holley, both had the same Comp extreme cam @241/247@050 - .545 on a 110. TTI headers were used with what looks like an 18” extension on the header.

The stroker produced 479 lbs of torque, 36.4 lbs. of more torque at a scant 200 rpm difference less @ 4K rpm, 8.5 more HP of 431 @ 300 rpm less @5500 than the 360.

The real difference is the torque curve. The stroker destroys the stock stroke 360 but a good bit more power.
The stroker torque curve decline doesn’t merge with the 360’s until approximately 5900 rpm. Where of course the HP is also the same.

So much for 273’s power rpm ranges he listed….
Keep dreaming 273, one day you’ll come around.
Perhaps you should actually build an engine and go to the dyno room for real life experience instead of “Theory” and put down your slide ruler and abacus. This way you’ll actually know something and won’t have to twist words, meanings and lead others on a messed up path sI h misleading words.

You are a piece of work.

I’m outta this stupid convo.


And that’s what wrong with those tests. Who build a 360 with the same cam as a 408?

I would have built the 360 to rpm as much as it could without cam timing that killed the bottom too bad.

But surely it wouldn’t have the same cam as the 408.

RPM is what makes the difference. They know this on that show, but it doesn’t fit the magazine narrative of dual plane intakes, split pattern cams and wide lobe centers.
