The bolts I used are GM part 12338064. My block is GM crate motor but as far as I know that doesn’t matter. Length of the starter bolts is 4.25” under head to end. If you look closely at the picture not only is it knurled but the shaft is actually a bit thicker than the threads and the threads have a slight taper.
