Hello, I am planning on taking out a LZ9 (gm 3.9L 3900) from a Chevy Uplander and put it on the engine stand to work on. I plan to purchase the Grade 8 mounting bolts (to attach LZ9 to the engine stand) in advance, but not sure of the correct bolt size. I read somewhere that the bolt size should be M12, as that would thread into the block, is this correct ? It would be the first time I am doing this with the GM V6 and wanted to have everything in hand ahead of time. Can someone please help confirm the correct bolt and thread pattern ?
Also if in fact it is M12, would the thread be M12 x 1 or is it M12 x 1.25 ? or perhaps M12 x 1.5 ?
Thanks in advance.
