Default Re: 1 of 2 Original 1969 ZL1 Corvette Blocks

I am not familiar with the aluminum engine blocks as to how they were machined, but I noticed that it has rotary cut marks on the deck pad where the numbers are. Did they use a rotary mill to surface the block or were they machined like the iron blocks which have the straightline machine marks?
