Why would Yenko or Dana convert an SS350? By March 1969 Yenko was on the hook for several hundred COPO 9561 Camaros. He could have easily had one shipped to DANA for less than it cost to convert one. How is a BV 4.10 axle ‘consistent with a big block’ when thousands of Z/28s were built with one? I spent 15 years involved with a Camaro parts business; repro Yenko emblems were available over 25 years ago. Also during that time we sold lots of original parts. YH & XT wheels, 837 alternators, BU & BV axles [2 BEs] DZ engines all installed on other cars. The presence of an original dated part on a restoration does not mean it was born there. All they are is “correct.”

The tach and dated axle leads me to speculate it may have been a Z/28 someone stuffed a 427 in. Long shot; check the top of the fuel tank for a broadcast copy.

I’m with GTO Don-I believe it is exactly what you were told-a clone.
