Compression shouldn't be too high with a 317 head. I'll bet it works out around 9.5:1. Also Autotec can build a flat or dish top piston for it. Rather than spend $$$ on a cast piston and machine work you would be better off just getting another stock short block and running that.

Because its roughly .120 over bore which depending on the core shift of the block can make it thin in the cylinders. It has been done several times in the past but it is best to have the block sonic checked first before boreing. In some cases a few guys have had blocks that had really thin cylinders after such a larger over bore.
He may not have ever done this on one of these engines and maybe concerned that under boost you could have issues.

Ill call tomorrow and see if he can sonic test. pistons for a 3.9 bore... There is more options.
