IIRC it was HH56 that had significant REpop piston problems in his Carib.
Yes, this was several years ago but one piston had issues and almost seized. Damaged the cylinder and was lucky to get last few blocks home with it squeeking.
Whether this was due to the piston or to improper clearances used, I cannot say for sure. I do know machinist was not impressed with the QC as they varied a bit in size, weight & finish but also think he might have used Packard specs for clearance and not the greater number several have mentioned being needed when using cast al pistons. I don't believe there was any paper other than an invoice that came with the pistons having recommended clearances so probably did use what was customary for OEM.
Anyway, those pistons were pulled and engine bored oversize for Chrysler 413's. So far, those are fine but the car is not driven much--one of the trailer queens except mine is a driveway queen--so not a true test. Several have mentioned Egge QC has improved considerably since then.
