For an extra $500 over a 302 boss block, there are several blocks that come with a 4.125 bore, and capable of quite a bit more overbore. Also you can get a 8.7" deck that can take quite a bit more stroke as well (never saw an intake advertised for this deck but certainly there is one). I hear that these blocks are quite a bit better than the Ford boss block - strength and oiling.

Just wanted you to look at all your options.
