If you go with a small block a great option would be picking up on a used W9/R3 motor. They are at 358 cubies and are lower compression and have sturdy blocks. I've seen them from about 12k -15k.

I would love an R motor, but this was merely about advantages or disadvantages of acquiring the displacement in different ways.
