We spoke to another Crower customer regarding the similar issues & here's what he had to say:
"I have had some of the same issues SPE has had recently. Our 2011 truck blew a motor shortly after installing an Industrial injection add a turbo kit and some 100 horse injectors. After wards we send a brand new crate motor down too Crower to have them design a set of rods for the 6.7 and ultimately our motor. That motor was at Crower for almost 8 months IIRC and they shipped it back to us assembled as a long block ready to go, it was looked over ( nothing measured ect just a quick glance as they said it was ready for heads and install ) and then finished final assembly and install in the truck. Truck ran great for about 1500 miles then started knocking, towed it back to the shop and tore it apart to find, you guessed it, a messed up piston, impact on all the rods from the squirters and one missing. Ended up sending the motor to Crower after months of arguing and them trying to give us the run around and them finally settling to pay us our time and them fix the issues with the rods. We received the long block a few months later and inspected it much closer this go round, we found pistons in backwards, rods look like they were clearance with an angle grinder and the kicker is the rods were still hitting the brand new squirtters we sent down with the block and they were still hitting. To add insult to injury they rebalanced the crank but messed it up so bad the only way we could use other rods like the Carillos SPE uses would be to replace the crank ( $1,000+ ). We have now taken the rods to a local shop and had them clearanced the rest of the way, ordered a new set of squirtters for the third time and are assembling everything in house."
The Fact that Crower is flat out saying they have no knowledge of impact on the squirtters is a straight up lie...
