That's not correct. The longer rod will dwell more at TDC, but less at BDC. Opposite is true for short rod. A short rod will also have a faster peak piston speed than a longer rod (not to be confused with mean piston speed). Shorter rod will have more demand at peak piston.

This is a slap.. your saying kart43 is incorrect, is Exactly what you said... both agree the longer rod will let the piston dwell longer at tdc, but less at bdc ....meaning the piston speed changes from accel to dell, ect in time.. Yet you are Confused in calling kart43 and yourself using the same mathmatical formula to both be wrong...... You sir are Incorrect, on being Incorrect... Here's your Sign COBB .
the others are wrong on stroke, in saying it moves the piston up .010, or More stroke will dwell at tdc & bdc. lol we wish,,... then the Second slap Sir was telling me to go look up graphs and charts, degrees arc, rod lenghts charts, because you found some new cool interweb site with all the charts, here's the SLAP,, When i posted longer rod, max stroke for this application every time. Pretty well says what your graphs and charts will recommend..... OK> back the to .010 more stroke moves the piston up .010 Wrong...> the piston or stroke would move up the wall .005, and .005 down..
Now to the other. sucks all the old Bob stuff is gone... Dynodon No one ever gave a critic an award... That's Funny.... WHY ? early morning roflmbo....
Clones have Dynodon Protection, and Barry's Affection !!! lol along with many others to Help here, iv'e shared all, and again, most info or stories, and data lost.. i feel like Sneak's.
but Death brings new life, and hope.. it has to, or there would be no continuation.
Back to Slapper,, i may be a nut in fantasy land, but i have that choice, here in America, at least where i'm at.. it's my choice to as you say , "slap" lol don't they do that in France ?
oh. back to original post, no machining needed other than the cylinder honed if wore. to diy build back is not hard, but if building back to rules, or specs. like akra bsp, then you will need the tools, .. degree wheel, dial iindicator, fixtures, burrette, no go gauges, and ect.. to make the measurements to know if it's truly legal wthin the specs, or rules..
question the dyno numbers, and tests you want, it will tell you a lot, in this situation, or application of engine, yes... you want the maximum amount of stroke allowed, and the longer +.010 rod for this application... . some blocks you only may use a .010 over max. crank to move the piston where you want +.005 up the bore.
KEY...these math arguments are really irreleavent to your question, some posts very rite, some vary wrong...
just have no more time to for these debates, certainly not an arc degrees, and piston speeds, and rod lenghts chart, ect.. which brings another point, every small change, can effect the tune of the engine package, installing the max. stroke crank, and +.010 over rod does effect the tune, is it better than before without a dyno proving it ? it should.. i
KEY 2... changing or increasing the dwell time, (as already stated above correctly by kart43 posted) is KEY 3.. piston timing to cam, & ignition timing in degrees, and getting the vlvs opened, and closed at the rite time is Most Important Key Here... These Events Tune Properly will put you up front, not that a dyno..
piston speeds, mean, average, acceleration/ deceleration rates, are all happening, they will do what they do, as a first time diy builder you need Guidance here from another builder, not math gurus, or charts, or dyno... become familiar with your motor, if already a mechanic, Great, if not Great. these guy's can guide you through as said...
