Does it run warm at all? the 6.7 I drive at work runs really warm some days

 

Very cool!

 

that is a beautiful sight, cant wait to see what that 1st gen will hit now. I've always wanted/thought about goin with a 6.7 motor

 

Wow Ron. You never stop amazing me!

Soooo, when do we get a list of part numbers, mods, etc?

That is flat SICK.

Congrats man, you have raised the bar for everyone!

 

I'm going to break the engine in over the next couple of weeks towing an equipment trailer up in the foothills. Then the engine and transmission are coming out and I am going to sell the First Gen. I'll either sell it minus engine and transmission, or with the old engine minus pump and turbo's. It's a pretty good hull as far as mechanicals go but i want something lighter.
The 6.7 is a new short block that's had a girdle, 625 main and head studs, Cunningham rods, and Hamilton 188/220 cam put in. Pistons are stock 6.7 with .030 deep valve reliefs , thermal coating on the tops and anti friction coating on the skirts. Balanced everything after lightening the wrist pins. Head is a stock 6.7 head that I sent to Greg Young at ZZ Fab in texas. he machined off the intake and made a new bolt on stock replacement one. Ported both sides and installed larger valves. It flows 40% more than the head on my 5.9.
It seems to run well and dropped some egt's over the 5.9 even though it ran fairly cool. At 70mph on flat ground I was seeing 600deg and on a couple of slight grades it appeared to be at least 100 deg cooler than the 5.9 running the same Gt 4094R / Gt55R twins with the same injectors and pump settings I dyno'd 1199 with.

 

more pictures more pictures more pictures more pictures.........

 

I do think this is the 1st street driven 6.7L p-pump. I think all others are in pulling engines.

 

very nice- been waiting to hear how this performs for you. keep us posted .

 

Just so y'all know, it can be done inexpensively, if you know what parts to use.
Use the right head and you won't even need to mill the intake off.

Mark.

 

How much lighter can you get? Dakota? Sorry to hear it you won't be in a gen 1 any more. Hope what ever you end up with you will be happy though. Good luck with the new build!

 

Got the fender straightened out and did a little tweaking today. Took it out this evening and ran it from here(600ft) up to Brownsville(a little over 2000ft). Ran really nice and smooth, and clean. Honestly, it looks like it could use some more fuel. Turbo's appear to be slightly less responsive according to the boost gauge. On flat ground at 60 it's just under 5psi with no movement on the primary gauge. They come up slowly like before and it seems like the primary starts making boost at about a pound or 2 higher on the manifold gauge. Egts are really nice. No problem keeping them down at 800 running briskly up the hill. Rolled it up to almost 30psi at one point and just kissed 900 before the top of the grade. It looks like the head porting may have taken away from the extra bottom end people claim from the 6.7, but it is burning cleaner and if I add a bit of fuel to the bottom it will probably perk the turbos right up. Got an oil leak to track down. I found that the pan bolts weren't very tight and that may be the culprit. I only have the vent in the valve cover and the small one on the front cover so it's probably pressurizing the internals a bit and finding weak spots to send oil through.

 

Can you get a vid?
