I have a question. A buddy of mine is interested in purchasing a hurt 3rd gen. Apparently the engine has rod knock and he tells me that he would like to install a 6.7 crank in it, if he can get it for cheap. After some discussion on the feasibility of this, and not getting into the 6.7 "Ag" crank, I know that the 6.7 as used in Dodge trucks doesn't have much additional throw than the 5.9 crank which means you won't gain much additional displacement by swapping cranks, and he would have to mill down the 5.9 pistons to clear the head…but this got me to thinking. I know the 6.7 uses larger diameter pistons, so the logical conclusion would be why not just bore out the block to accept the 6.7 pistons? Or is it not that simple? So questions. Is there enough "meat" in the cylinder walls to bore out the .20 something needed for the 6.7 pistons? And, does the 5.9 and 6.7 blocks have the same deck height?? I know it's probably easier to just use a 6.7 block, but it's more of a curiosity thing
Thanks Ed
