Sorry it took so long my contact was on vacation. Your engine was built in Spring Hill Tennessee. Thanks Firehawk99 I just crawled under and took a picture of my Julian tag and it starts with N and I was going to ask the same question. May 12th 2021 for me and Vin build date is 6/21 so it looks like it's running about 3 weeks to a month difference from engine build to truck build. Thanks again for all your info.
