So guys I've been away for a while. been real busy with school so haven't been around a lot lately but i've got a serious question. Now dont think i'm just being an idiot trying to go for a big bore. those of you that really look at this and notice the specs will probably see what i'm trying to do. i've rebuilt engines plenty but have never done any boring of any sorts so i dont really know a whole lot about it. my question is how much can the 7.3 be bored SAFELY while still keeping reliability? i'm lookin for .080 exactly per cylinder. and if i could find pistons and rings to do it.

 

i don't think you can go that big. most of the time it's .030 over

 

why .080? biggest i think i have seen was .060 and i might be making that up.

 

I saw the .060 but the reason for .080 is square bore/stroke but after more research I'm not sure square is the route I want. Possibly more stroke for the torque theory. Any way to do that really?

 

there is a stroked crank on powerstroke army for sale
