You have to go to a marine/industrial dealer not a regular GM dealer. I have access to the Marine/ind catalog but I cannot log into it today.

Yes i am quoting myself.

The 8.0L marine/industrial engine still at least per the catalog uses a 1/2-20 1/38" bolt, p/n 10126796.
Thanks for looking it up. This one is different oddly. Wish would have paid better attention when I still had second one that had the balancer.

Bringing this back up. I made a big mistake on not getting the measurement done and just going with what was told on the bolt thay did fit. Actual bolt that this motor uses is 16M x2. Same thread size as what ls motors use, but washer needs to be a 57mm OD. Total depth is about 117mm
