My motor is going to be getting a rebuild after a mystery failure and I figure with the turbo going on now would be a good time to do a little upgrading on the bottom end. But honestly, the sizes of everything has me completely confused. This is going to be a stock cube rebuild, just bringing the block into the machine shop for redecking, mild honing, cleaning, and the bare amount of machine work necessary. I've been looking through about every website on the planet that sells rod and pistons for these motors and I think I have an idea of what I want and wanted to check with you guys to make sure all of the sizes are correct.

The connecting rods will be 6.125" Scat I-beams with ARP 7/16" cap screw bolts. $284 for rods with ARP bolts? Sign me up.

The pistons I've been a little more back and forth on. My first choice is Mahle -9cc dished pistons. 3.908" bore 3.622" stroke
These come with the wrist pins and piston rings, so for the $665 they seem to be a good deal.
I think the -9cc dish should be just fine for my level of boost. -16cc almost seems a little extreme for the level of boost I'm planning on running.

BUT OF COURSE, I was on fleabay the other day and noticed these

Lunatis for $350? But these are for 4.125" bore and are a -17cc dish. Will these work in my stock cube motor? Seems like the bore isn't for a 346/347.

I was just hoping someone could look at the measurements of the rods and pistons and let me know if I need to order something else based on the matchup or if I'm good to go. Thanks guys!
