If I were to bore my 3400 to .40 over what all would I have to replace? Do they make a kit? If not know of any good sites to look for the parts I'd need?
yeah, 60degreev6 is hands down the most comprehensive site for the 3400, with domesticcrew and v6z24.com coming in after that. Basically though, if you're boring over, you'll need new pistons sized to match, and new rings. Thats really about it.

Might wanna check with them first to see if you can safely bore the engine that far over.
