Ok, as we understand COPO cars, the blocks and Heads are understood unless otherwise doc'd. Muncies as supplied via GM as they were given, Intakes, carbs, water pumps, etc..etc...etc....
Have we ever done a full documentary on all BE's in every known existing car on the lists???
Is there any discrepancies on the BE at all throughout the build assmebly that would show anything unusual????
So many things occured back then, variations, etc between many RPO's;
Could there be any variances to the BE whatsoever?
