ive aquired five good 6.7L pistons and one bad. as far as i can tell compared toa 5.9 the pin is the same height the same and the only difference is diameter the 5.9L is 102 mm and 6.7 is 107mm, i know if i rebuild mine i will need to bore it, so i would like to buy one 6.7L piston and stick them in. just wondering if there is enough block to punch it to 107mm. havent found anyone who has done it but im sure if it can be done someone has. would make it a 6.5L or 395 ci.

 

It won't work, a 6.7l block dimentions n stuff are the same but there's one less water jacket in between two cylinders to fit the bigger bore, you can run 6.7l rods n get a 6.2l displacement but not pistons.

 

I'm AssuMing You Mean ThE Crank Bc Changing The RoDs Just Changes Piston Height Not stroke

 

yeah my bad.

 

running the 6.7l crank will also require some pretty costly pistons to make it work correctly
