Ok, so there have been a ton of threads about the 6.4 and although relatively informative for the most part, they tend to trail off into the somewhat vague area of leaving people to either go to particular shops that build them on a regular basis, or go off of the general 0.060"-0.080" off the deck and run with it using the 5.9 crank in a 6.7.
My question here for those with information pertaining to the OTHER ways of going about it, would you mind sharing what you have?
The original plan for my build was a built 6.7 with billet rods, massively ported head, etc etc etc. My donor block came from a truck with a stuck EGR and gummed up the entire thing, and I mean ALL of it. Upon teardown it was discovered that when it gummed up, it decided to take out a rod bearing and FUBAR'd the crank journal. SO, the decision was made to destroke it with a 5.9 crank and go about our rat killing.
So I ask you, if running longer rods, as opposed to decking the block, what is the general (or exact if known and willing to share) length of rod needed? I've heard 205-207 mm thrown out there, but it was never expanded on further.
I've already spoken with a couple manufacturers of billet rods and gotten quotes, and from current perspective between cost and increased longevity of the build, this is looking to be the best/smartest way to go.
Now to add to this, like before, while mentioned vaguely, the subject of ideal piston design whether stock, stock marine, modified stock, custom. What is the most ideal if anyone cares to share for a 200% over injector, 194/220 cam and a highly worked over head with oversized valves and lots of porting?
Thanks to anyone willing to share ANY information on making this happen.
