Motor Mount Thread Size (LS1 Block)

Pulled motor out and threads on one clamshell to block bolt came apart. Anyone know what thread size is? I am looking to Heli-coil it.

Remember they are blind holes. Get too crazy with it and you'll punch a water jacket and have problems

Mine was put in straight with motor out of the car so I guess heat or torque did something. I will post up results later this week, but it shouldn't be a problem to helicoil it.
