Bolting Engine to Stand

Bolts are 3/8 NC and I use 4" long grade 6 with a washer against the engine stand. My engine stand is 3 inch thick where it bolts to the engine, so check to see if yours is the same, and just add an inch to get bolt length. Two bolts you will need nuts for them as they bolt through the block where there is no thread.
I think thats right, but then again it's midnight here!
