One thing you need to consider is the date code and casting code on the block you are going to use. The casting code is helpful in identifiying the block, but the BAR will look at the assembly date code (stamped in) to identify when the engine was built and you will need to comply with the smog requirements of the assemby date code.

I went with a 1965 289. This got me the desireable six-bolt bellhousing, and limits my need for smog equipment to a PCV valve.

By the way, you don't "beat" the CA smog, you "comply".
