Here's one from an L48 350 out of a 70 Chevelle. VIN sequence begins with "1L0..." That's different than what's been posted so far. And yes, this is a 70 engine as the CRE code was not used in 1971.
*Update - I just realized that this pic is from a 70 Monte Carlo that I took a while back. Maybe that explains the difference in the first three digits' sequence
