I'm looking for a rod bolt stretch guage for when i put my engine back together but have no clue about measuring equipment as this is my first build and i've never needed any of it before. I've seen a few on ebay for Chevy's but they look qute big and not sure wether they will fit in the botom end once everything is back together.

Have you got any recomendations or makes to stay away from?

 

Woops wrong section, i'll repost in the all motor section
