Coremake & casting pours of the 2017 '537 block & 2010i 961 block will overlap for a short period in Defiance during build out of 2010 and ramp up of 2017. The cores have no easy identifiers to distinguish the model years between one another. To aid production in identifying the core assemblies add RPO code 'L5P' to the backside of the G, H, L, R, J, & K cores. Secondly, update the '537 cope valley suffix from the Gamma 'C' designation to '4'. This is to match the P-release casting file revision.
