I was removing my pistons from the engine block, this one fell to the ground. It got this little ding on the edge, it didn't really lose any material, it just pushed it down. There is a small bulge where it was pushed down. I doubt that the bulge would contact the cylinder wall, it might be close though.
What to do? I'd hate to have to buy a whole new set of pistons because of this.
The piston is a Ross blower piston. Too bad the shadow concealed the side details.

No way would I run that. Contact Ross about replacing a single piston, most manufacturers will sell them individually.
Maybe if that was in the middle of the piston, then I wouldnt worry about it. Being on the edge like that...

Yikes. The piston was machined to bring it down to 9:1 compression. I could probably get a new piston, I'm guessing the machine work would be somewhat hard to duplicate. The shop that did this originally is long gone.

^ +1 to Ws6nightmare. Give them the piston to duplicate. I'm sure it wasn't a CNC program that did that piston. Very easy to CC a piston for anyone that has done it previously.

I spoke with the Ross tech. He seemed to think it was not a big deal at all, it just needed to be smoothed out with a scotchbrite pad. I still have mixed feeelings on this. I am taking a block to a speed shop for some work, I'll see what they have to say about it.
Randy is correct, they have a minimum order of 4. They said that my part number (63494G) indicates that it was a custom set. I doubt that. It looks exactly like their off the shelf FI piston. I do have to say they are nice pieces though.

I will go against the grain here, I think it will be fine. You just need to take a file to it, and make sure nothing protrudes from the side and then smooth it with some scotchbrite.
