340 Crank bolt threads issue

Locomotion said
All small block Mopar balancer/damper bolts have the same thread. Damage can be caused by trying to install a tight balancer/damper using a stock length bolt and very few threads are engaging. I bought a longer bolt to get it started so more threads were engaged before it started pulling the balancer/damper in.

Or use the proper tool. A little overkill for a 1 time use but they may have them available to use at the parts store or you can rent from the rent all.
