Cool car, although the rear being jacked up to clear the 3" pipes spoils the look for me. Most likely not a real L78 with an 01A cowl tag date, the 6K redline tach may have been added along with other L78 specific parts. 2Q indicates M21 so it was at least an L34 360 HP. Paint is a bit rough but what's not to like about a AA code black '66 SS, wouldn't surprise me if it has already changed ownership.

The car is sold. The owner of the car had contacted me awhile back about it. Not a real L78 car, tach was added, rear end are factory 3.31 and m-21 block is from 70. neat solid fast car, paint was a 6-7 but hey black/Black 4 speed pretty cool!

Con VIN stamped on it's 1970 L-78 engine block is 131778.Owner wouldn't divulge any more.
The fact that they only produced the 1970 L-78 Chevelle/Elco for a brief time very early during 1970 production,it has to be from either the Kansas City Leeds plant,(K),or Van Nuys assembly plant,(L),or a 1970 L-78 Nova @ Willow Run,(W).
1970 Camaro VINs started @ 500000,so that rules it out.

I went and looked at it yesterday. The L78 currently in it is from a Nova. Cool car but needs a lot of cosmetic work.
