Is there such a car?? 69 Chevelle question

[quick-bowtie]

A friend of mine has pictures of a 69' Chevelle Orange Altered wheel base L78, A guy is trying to do a deal with him on some cars, this guy claims the Chevelle is a factory experimental car here is the info

Claims GM made 2 or 3 of the and has direct contact with a X-GM engineer who claims it to be real, GM guy also said they did a couple buicks like this to.

The motor and front suspension are set back about 2 inches (which he claims is factory) it also has a big fan should that looks like it could be factory for such an application.

and there is also has a plentium air cleaner which isnt the style Ive seen on the camaros and some chevelles, the me the air cleaner kind of looks homemade but who knows..

Thought Id ask the experts has anyone heard of such a car? altered wheel base L78?

Im hoping to post pics but his files are WAY to big so it might take me a day or 2 until I can get one of his guy to resize them.
