If I wanted an FIA with a small block (right choice, BTW), I would do a short deck stroker. Maybe start with a 4.125" bore Dart block with an 8.2" deck. This way you could get big cubes and no one would know that it wasn't a 289 or a 302, because it would appear the same on the outside.

A 3.400" stroke with that bore would yield about 363ci, 368ci if you went with a 4.155" bore.

IMO, you could have your cake and eat it too. The more cubes you have, the more power you can make without making reliability sacrificices....plus you would have an engine that looks like a 289 from the outside. You can tell the difference between a 289/302 and a 351W just by looking at it. A Windsor block is considerably wider and taller.
