The chattering look of the grind out appears exactly the same as the grind out and restamp on my brother's 30k mile survivor 1973 Corvette L82.
I have some 1970 ZR1 grind outs which you would laugh at (just the last letter dished out).
Most of the ZR1's were converted CTU LT1's which already had the larger oil pans.
Seems in 1971 -72 they would gang stamp all but the last suffix letter (especially late in the year) so the engine application could be SET after build up WITHOUT grinding out.
EX. from my 71 LT1
