How Robust is the 318 block?

MonkeyMadness said
I picked up a fresh rebuilt 72 318LA (hasn't been run since the build) from an estate sale. Pulled it apart and found the block had been bored .060 over 3.970"
Block looks really good and seems to have been prepped well.
I was planning on dropping a 390 stroker kit in this block and just wounding if these 318 blocks can take a .060+/- over bore?

Depends on the block, seen a few with a 4" bore.
Mine is .060" over but was sonic tested first - thinnest cylinder is .167" on the thrust side (73 block). With a 4" stroke I would stick with smaller bore if possible but have it checked - you might get away with it.

can 340 main caps be used on a 318 after a line hone?

I would think so if you are getting the main tunnel align bored - but I could be wrong.
