Has anyone bored out a 272 are there parts available for a bore out. 20 or 30 over any feed back would be great.

 

JMO, but if you were to post this on the Y block forum of this site you might get a lot more good information. Might help if you re-title the post so someone has an idea what you are asking about without opening the thread. Maybe a mod will move this. There are parts available to bore a 272 oversize. I have bored a 292 to oversize and I believe some 272 blocks will bore to 292. And parts are available but expensive.

 

These are the factory O/S pistons available
