I'm curious on how the engine is set-up as well? It would be interesting to see how everything works.

The pistons are stock 6.7 pistons that have been cut slightly and coated. This work was done by Greg Hogue. The cam is a max spool custom, also created by Greg. He also did the pushrods and lifters. The engine was honed out slightly to make the pistons "loose" in the holes. The head is O-Ringed, and port matched. There are 14mm studs holding it all together. The rods are 12v peened and cryo'd and the crank has been edged etc.

thats the basics of it

Mike Holmen

Sounds like a pretty stout set-up buddy.

Blueboy

Did you have rods peened and cryo'd.
I have a set I need same thing, I need
a place to send them.

Should also get the crank/block cyroed as well. Anybody locally do the cyro? I found a place in near Salt Lake that's not to expensive.

I might do a quad trip down there, while the engine gets cyroed.

Blueboy

Mike,
I just talked to Bobby.
You were right cost for cryo is cheap.
He will call me back this afternoon
on price for shot peening.
I will get them in mail today.
thank you.

my crank is cryo'd too, not the block though

Blueboy

I need to get a new set of pistons,
does anyone know if the Bowl is
the same on marine pistons verses
stock piston for the same year.

Here is a modified 6.7 piston for sale on comp D

I saw that there was a few cranks for sale as well, cheap.

What you building? If its a 12v, you can score new marine pistons for around $500

I've been do some web shopping as well

Mike Holmen

Kev, what size injectors you running? They make some big stuff, these days. I was supprised that I told one shop that I had a 70LPM injectors, they laughed. The stuff thats available today flows way more than that old stuff. I might spring for a set of 6X18 injectors

Blueboy

Mike,
The pistons will be for motor in my sig.
I looked at those,s pistons. not sure
if bowl is to small for my injector pattern.

I have a really big set of F1's, secret even to me,, lol Don calls them Flux 8.5's

Mike Holmen

Which and how he doing the nozzle? I guess we have to see, never know with this stuff. someone would get mad if you flow test them right? Have you if heard that you can use a larger nozzle in the head.

Kev, you know how the bottom end is done in your motor? Studs and girdle. I want to see how the 14mm studs are at keeping the boost inside the motor. I seem to run into head gasket issues in the past.

Mike Holmen

Blueboy, you looking to get pistons for the 05 truck? I don't think that the 6.7L piston would fit. The 6.7L crank is suppose to fit, but then you'll need a custom piston, if you run a 5.9L piston. I would run 12v or a 24v rod (24v rods are suppose to be the best).

Here is a pic of the extra parts that I will be putting on. Got them back from the Powdercoater. Sorry they are still wrapped in plastic, I didnt want any overspray to get on them
