they were smart to make the engine look right--a repro set of valve covers is about $70, and a repro oil pan (and this is the right repro, but the oil temp sender isn't there, that and not beat up makes it a repro 
) is also available. The air cleaner first looked right to me--but I think it is a nice job at a replacement. I don't remember the barn-find video even showing the engine.
My 3rd favorite thing on the car--the texture on the support bars between the rear fenders and the B column (the one above the correct fuel cap)...I am still amazed at Denis' texture on his air cleaners, that and the undercoating splatter in the engine bay are 2 things I do not dare to try....but I'm going to have a stab at those...some day.
Vin? Love to hear if someone knows, I'm going to take a swing at 8ma924, if someone says higher or lower and gives me another 3 chances.... 
Provamo has this as "unknown 1391", interestingly dated 2018, without the spoiler on the front...and the barnfind video posted March 2021...Would be curious when it was moved to the 'barn''...Lee
