400 stroker

Yea, I'm pretty sure you will need to get the pistons and rods swapped around. If you just switch the pistons to the other side, the pistons would be in right, but then the rods would be backwards. :BangHead: That's why I try to do as much of my own work as possible. Good luck! Let us know what happens!
I will. I just hope they're floating pins because after this, I don't want them touching anything. I know the rods are pointing the right direction because I know the squirter holes need to be pointing towards the center. I too hate having to have others touch anything because of stuff like this. This is the first engine that has ever been screwed up. I usually just hone the cylinders, add rings and bearing and put it back together. This was the first engine I had bored and was taking time on. They screwed up and now I have to fix it.
