No X33 COPOs. "A" suffix Muncie = M20. Only one of those documented (mine
). Wrong rearend: BU not BE. MN code engine should have #840 cast iron heads. The VIN number is close to only one L-72 Camaro on Ed C's site -- a Yenko sold at Nankivell. As we all know, Yenko only ordered M21 or M22 4 speed cars.
Also, if the guy can't find anything else to change on the car to make it better, why isn't it a 10 out of 10?
With reference to the casting date on the engine vs. assembly date, I remember reading somewhere that 512 and other performance blocks often had longer gaps between casting and assembly due batch casting but less frequent use in cars??
