I am about to purchase a 406 fe block that has been sitting outside and has some rust in bores. I think it was bored to .060 over and I would like to know if I should proceed to acquire it and what problems I might encounter if I get it if any? I think it was in a jet boat.

Like if too much taper can I bore it further? Like to .080?

Or if too rusty.

As I take this block to the machine shop what should I have checked before proceeding?

This block has the thick webs and side provisions for cross bolts. I have seen on ebay a bottom girdle for fe's. Any thoughts on how that would work vs/ having cross bolts installed.

Any starting suggestions would be greatly appreciated.

I'm a newby!
