value of a ZL 1 clone with a real ZL1 motor

[69LM1]

Tomorrow is the last day of the crusin the coast show, I'll be heading home then. I bought a gasket set!

There are estimated to be over 6,000 classic cars this year, one of the best showings ever. Many 69's and a lot of hemi cuda's and clones. The car corral and swap meet was pretty dismal this year. Everyone's parts were ruined by the hurricane. Some of you northerners should come down next year, you'd make a killing!

Two respected people in the hobby have looked at pictures of the stamp (and I need to stress that it was just pics, they or one of them need to see it in person) and at first glance, the stamp seems to be in line with other MP stamps from that time frame. Cast and assembly dates line up, not sure if the chevelle VIN and assembly dates line up, anyone know dates ranges on chevelle vins?

The head will come off early next week, and I should know more.

Real question is that everyone seems to agree that it is a L72 engine, if so, what could it have been out of if not the chevelle whose vin is stamped by the oil filter? I have learned to start by attempting to find the (or not so) obvious and disprove first, then work on proving.
