That'll learn me to formulate (and send) arguments at five ayem....

3A and ABA both have the same bore and stroke rendering my premise mistaken.
The word on the street (VW Vortex) is that the ABA has 16 mm longer
connecting rods. However, I've learned my lesson. I ain't saying nothing
until I measure them.

I selected the ABA because it was available. 3As are not in Eastern Orygun.
I figure if I have my selection of half a dozen ABAs in a small town here,
they should be reasonably findable in Kansas or Wyoming.

Additional considerations included the differences between the 3a and
the ABA. The 3A gains its displacement by using larger pistons.

ABA 115hp@5400 rpm 135 ft/lbs@3200 Motronic
3A 115hp@5400 rpm 122 ft/lbs@3200 CIS-E

10% difference.
