How does cid make power?

In some case your limiting the two engines by the same top end. If you increase the displacement then be an equal percentage you should increase everything else to match.

On a twin bore size engine, the stroke makes different displacements. What are we talking about here?
A .040 inch over 360 vs a 040 hour ver 360 w/ 4 inch stroke?

Engine masters did this test. The stroker made huge torque over the 360 and at the max power output, only a few hundred rpm’s down, just a couple of hp.

I think the episode was “Stock vs stroked.”

And if you line up the power curves both from the peak like you would with proper gearing this the actual hp ish difference from what i can see.


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

To me shows No real gain, this is what i've been basically saying with increased displacement it just works out even or it should. Obviously this is just one build not overall proof.
