Un-stroked vs Stroked Displacement vs. Crank Angle, etc.

a couple of degrees here a couple of degrees there it all adds up
always a suggestion to advance a cam 4 degrees
a couple of things
The change of dwell - piston movement per crank degree around tdc long rod is slower than short rod- short rod gets the piston moving quicker- affects overlap TIME
piston movement around bdc short rod is much slower than long rod- cam timing for intake close and ex open does not make as much difference
so we get to piston flow demand around TDC , capturing power with exhaust opening- can be later with long rod and dynamic compression- more critical intake close with long rod
only a few degrees but at 4 different places
now throw in cam acceleration with the larger mopar lifter
