Un-stroked vs Stroked Displacement vs. Crank Angle, etc.
Uh-oh... I realized I made a mistake in my conclusion about the LSA. My brain was putting the exhaust stroke after the intake stroke ....WHOOPS! So, with the exhaust's peak displacement rate occurring later in the exhaust stroke, and the intake's peak displacement rate occurring earlier in the intake stroke, then it seems like NARROWING the LSA by a couple of degrees the thing to do.
Pretty interesting. And not to say your info is not useful.......it certainly is and thanks for posting........but to me this further shows that rod length has a minimum impact on what an engine does. You'll never feel the difference on the seat of the pants......or see it on a dyno other than perhaps a different curve.
Yep, I cannot argue with you, based on this. All this started with some info that cams would change with different SB designs, and I just got to wondering 'how much' does it change, and it seems like not a lot.
Now as far as a complete answer for rod length effects, I don't think that has been 100% answered here. If you changed the rod length a significant part of inch, instead of the mere .4123" here, then things might start looking different. For example, the change in rod lengths for a /6 stoker design that has been around for a long time change the rod length about a full inch, and that may make more significant changes.
