The difference between Inline and Vee configuration is largely about balancing of the rotating assembly. Rod Ratio affects the dynamics within each cylinder independent of layout - piston speed; side loading/slap etc. Some suggest that this variable is perhaps the last one worth worrying about:

especially in a relatively slow turning street application.

Now when one is designing an engine from scratch to rev like gang busters (motor cycles, F1 , Indy) then long rods buy you piston dwell at TDC - useful on both compression and exhaust strokes

But as the Victory Tech papers instruct - in a slow turning street engine the short rod is your friend. The added piston speed off TDC makes better use of multi-carbs and provides low end torque. One strokes to add displacement - why give it back with a longer rod?
