Can a small block timing chain jump a tooth?

15* is a lot on a timing chain. To answer your question, yes the chain tensioner will bolt on a LA block. It replaces the cam plate. It's a nice upgrade that keeps all of the slack out of the chain as it stretches. Some people say it's a waste . I put them in every engine I have apart. Keeps your timing rock solid.

I have always been concerned about plastic shavings from the tensioner. Maybe not such a big deal after all, I don't know.

I do know it takes a while to stretch a good double roller timing chain enough to make it a problem though.

If the block has been line bored and has excessive clearance I guess either a shorter chain setup or tensioner would be needed.
