The old (c. 1990-1995) 347 kits used to have issues. The biggest culprit was using a stock low-tension ring package...resulting in some oil blowby. This is due to the different geometry of a 347 stroke putting a little more side-load on the piston. The only thing you will see on a 347 (and even a 331) is a little more scuffing of the piston skirts when you rebuild or disassemble it...again, due to the side-loading.

I say if you're gonna do it, go with the 347. The oil-ring runs through the piston pin on both, so go with a little more stroke. They make sick power and torque. Just make sure to get a nice set of rings.
