I tried to include other pictures showing the pertinent numbers but they didn't attach...here is the VIN stamping.
I'm no expert on broach marks so you could be right about the lack of broach marks. Although it didn't have the look of a block that had been entirely surfaced nor have the "fakey" broach marks added. Besides the casting date of the block jiving with the car I thought the location of the VIN stamp (by the oil filter) was more legit. Or put another way, if someone were to go to the trouble to locate a date correct block, surface and stamp a plausable build date why not stamp the partial VIN next to the build date as well? (instead of hidden down on the oil filter boss)... Perhaps someone else will chime in with an opinion.
the car did have a plausible date on the carb, a proper intake, wrong heads (dart heads originally now 186's) but a correct bottom end as well. So at least someone went to great lengths to fake the car if it is fake...he bought it 6 or 7 years ago so before teh market went totally insane (BTW it does have an X-33 code on the trim tag)
PS I realize the VIN is nearly impossible to see in the photo but in "real life" one can make out the numbers
