John's 66 Dart GT covertible restoration

I took the block down to a bare block, it took a little moving back and forth of the pistons to get them out. I labeled everything so I can put it all back where it was from the previous build and/or factory.

I did notice a few scrathes if you want to call them that in the bores. Maybe 2. I will post pictures of them to see what you guys think. I really would like to keep the 273, but if I would have to bore it over I would just swap in a 318 or 360.

How much can you hone the 273 with either a stone or dingle berry hone? Also what is a good cylinder to piston clearance or to much of a clearance? I appreciate it guys
