I was on the fence about this as well until I measured the size of a modular motor and decided I really do like my knuckles. It is bigger than a 385 series motor, except in length and does not deliver the gut wrenching pull of a 385 series.

I am going W on my build. 9.5" deck, 4 1/8" bore, 3.85" stroke. Should motivate my car pretty well and be very reliable.

For me, it ended up about having enough room in the engine compartment to work on it without losing a pint of blood every time I turned a wrench. It also affords me the option to open the foot wells up a bit more.

Your decision should be driven by your own criteria, as your criteria may not be equal to others.
