Just got my Gsr block bored for 84mm Endyne pistons. I checked the rings gaps and i'm getting .017 with feeler gage. Endyne is saying on the sheet that came with the pistons that they should be .012=.013 for 84.5 bore. I checked the all the sizes with a intrimike from work and all the bore sizes were 3.308 minus a few tenths. I this going to be a problems or not? I already did a search on here and could find anything good to go on. Please help so i can try and get my block together this week.

 

You will experience no problems at .017"

 

Thanks alot Earl. U think i should double check anything else on my block before i start assembling it?

 

Check everything you can, twice

 

that is what i would do
