Sounds like a cool project! :-) To answer some of your questions:
The 360 isn't all stroke, it does have a larger bore. The 318's
bore and stroke is 3.91x3.31 and the 360 is 4.00x3.58. I'm not sure
about the block on the 6, but if its like the 318, it isn't very thick.
Max overbore on both the 318 and the 360 appears to be .040". The v6's
bore and stroke is the same as the 318. I've heard of 318s that have been
stroked to 340's, so I guess you could use the same components to make
the 238 a 254...
Were you looking to stay naturally aspirated? The easy way out is
a supercharger, nitrous, turbo... :-)
