I am going to be pulling my engine tomorrow and need to get my engine stand adapter finished up (similar to the Pineapple Racing adapter). I welded up an adapter out of some really thick steel, but need to get the holes drilled to attach to the engine itself and the engine stand. What size diameter are the studs on the engine so I know what size drill bit I need for making the holes?

 

The larger of the 2 front studs on my cosmo is 0.470"

a half inch drill and you should be fine

 

Thanks, that's exactly what I was looking for.
