C4 to block bolt size needed

Bought my engine and trans separate from each other and was wondering what is the correct bolt length. If anybody has this info handy I would appreciate it.
 
Bolt length is dependent on which C 4 you have. Some had thicker bell housing mounts. I like to see 3/4 inch of bolt in the block, but check the depth of the holes in your block.
