I recently picked up a 408 stocker. After removing it from the create I started a thorough inspection of the engine. Using my bore scope I noticed piston skirt scratches on some of the cylinder walls. None of them look deeper than the cross hatching pattern. I called manufacturer and they told me it was nothing to worry about. In the last two years I rebuild a 340 and 360 and after a 500 mile break in I seen some very very minor scratches on two the cylinders on the La 360. In my experience of over 40 years of rebuilding engines as a classic car collector there are two causes for this, improper clearances or unsanitary conditions on assembly. I am by no means a guru on rebuilding engines but very precise on my builds and on the 40 or more engines I have built over the past 45 years have never had one fail. In my opinion I don't see this as normal, maybe some very very minor scratches on one or two cylinders but 6 out of eight concerns me somewhat. This engine has less than a 100 miles on it and runs very strong, It dyno at 500.2 hp with 523 on torque. I am very anxious to get it through the break in period and give it a run through the gears. Thinking about asking them warranty it but dam I hate to pull it after all that work. Have few buddies who have bought them without any issues and love them. I didn't mention the manufacturer because they have been very helpful and have a state of the art facility.
