I am freshening up my 347 with a hone and new rings. Pistons still have .005 clearance as recommended.
I have Probe #10660-40 pistons and ordered Summit Racing's .040 rings to install. I went to measure the end gap on the top ring and came up with .030! The Perfect Circle used rings I just pulled have .020 gap currently! They started at .016 as recommended by Probe. Any suggestion on why new rings are measuring this way?
Thanks
Tom
