I read the article on it, we'll see if other engine builders pick up on doing this or not

 

that was an interesting read. very cool.

i know this is the 6pointoooohhh forum,
but are there stroker options for the 7.3 ?
i'm assuming with most all custom parts.

 

i dont think they offer it for the 7.3, only the 6 leaker.

but call them up.

 

that's cool as heck

 

I am in love

 

I bet it's at least 10k
did anyone see pricing ?

 

Although that is a NEW article.....that's not a NEW development. They've actually had that in production (more/less) since 2013 to my knowledge, although it looks like they've come a long way in getting to use all Ford parts. The power potential of that engine is big, but what the "uncertainty" of it was the longevity. Maybe now that they went through having their engine published and advertised, it's been a proven enough concept and would be a good all-around engine rather than just being a competition only engine. J&K also didn't have a very good reputation for awhile.....horrible customer service issues. 4 years later though, who knows?

Edit: They may have a "reboot" going on, and that's why they chose to do the article......to bring interested customers back and show them that they're better now. If I had the funds I'd definitely try them out. The short block price starts just over $6k, and is special order only.

 

I think its awesome that this motor is started to come back around in popularity. This article in diesel power definitely will help.

Maybe I'll keep holding on to mine and the resale value will start going up rather than down, lol

 

And this might just be me being a picky bastard but making a big deal on how the rotating assembly is "precision balanced and machined" and then showing a picture of the notched piston that looks like they went to it with an angle grinder or a file kinda rubs me the wrong way.

 

Yeah, that hack job on the piston makes me wonder. Maybe they should have Industrial Machine and Tool do the work on them as well.

But, when I win the lottery I'll take one of these, some UCF heads, stage 2 cam, Odawg ported intake, BPD oil cooler, built trans, high volume HPOP, and my KC Stage 2 along with some fuel mods.

 

I'm thinking about buying another 6.0 and I'd like to snag one at a low price and throw this motor in it. :woot:

It looks interesting, just wonder how the reliability is on it?

 

Just for reference and conversation's sake....

Video posted 3 years ago.....

 

Really , all that promotion hoop la and you let a picture close up like that get out in a national magazine . By the way those pistons were
precision cut with 1/2" wide jaw Vice - grips , one chunk at a time ! No air grinders needed .

 

Why, when you cpuld spend 6k on better 6.0 internals and turbos and fuel and get the same?

 

I love the idea of it, with the extra cubic inches especially with the longer stroke it has the potential to really make some sweet low end torque numbers and streetable power. Now take that "better" base platform, and put your top end upgrades on and hold the f on.

I think the execution could be better with what's been brought up here.....that being said....if it proves to be a good platform then all the little things we've brought up thus far may be moot. It shall be interesting to see.

 

Nvm I'm an idiot, i thought changing the stroke meant machining the block,

So 6k for some internals, that still sounds high

 

So 6k for some internals, that still sounds high

This!!^^^

Especially since the 6.0 pistons/ bottom end is (I'll go ahead and say it...) stronger then a 6.4. The .4 of a liter is not going to be ground breaking diffrence in power.....now if they make a GOOD 7.3 Stroker kit, or bigger, it might be a better investment. As the article says "the bottom ends can handle 900+hp". US 6.4 guys can't say that thanks to the hollowed out slugs we have, but the solid 6.0 slugs can handle some major abuse.

I like lamp...

 

they might have to clearance the block ?

they do line bore it for the 6.4 crank

 

I requested a quote on this engine as I am doing research since I may be in need of a replacement engine soon. I was told $12,500. I also got a build sheet. I will try to paste it here but not sure if it will work since I am on my phone:

“The J&K PowerstrokeR”
Designed and built by J&K Engines

DESCRIPTION: We bored and stroked a 6.0 liter Power Stroke to a 6.3 liter making it 383 cu.in. More displacement resulted in dramatic gains in horsepower and torque! The entire rotating assembly has been Blue Printed and Balanced and Dyno tested with results. We stroked our 2004 F-250 utility truck with no upgrades, just simply a stock configuration.

RESULTS: stock 6.0 f-250
270 HP @ 3300 rpm (at the wheels)
485 ft lbs of torque @ 2000 rpm (at the wheels)

RESULTS: 6.3 “ Powerstroke’R”
446 HP @ 3125 rpm (at the wheels)
850 ft lb of torque @ 2670 rpm (at the wheels)

The “6.3 Powerstroke’R” gained 176 horses and 365 ft. lbs of torque!
These dramatic power gains are based on NO modifications to the stock 2004 F-250. With a 2.5 inch exhaust. Any mods that anyone does to this platform will increase the HP and torque even more.

COMPONENTS AND PROCESS:

• 6.0 liter block bored .040
• Oil galley plugs tapped and screwed in.
• 2010 6.4 Power Stroke crankshaft custom machined and balanced.
• Connecting rods, honed and balanced.
• .040 Mahle pistons, milled, notched and balanced. Pistons tops are ceramic coated and skirts are also coated by PolyDyn, check them out, Performance coatings by Polydyn.
• G-rotor, for low pressure oil pump is custom machined.
• Front engine cover is custom machined to fit 2010 6.4 Power Stroke crank shaft.
• G-rotor cover custom machined.
• Harmonic balancer is machined and balanced.
• Flex plate balanced.
• Mains, rod and cam bearings are coated by PolyDyn, for longer life and less wear, Performance coatings by Polydyn.
• Rear engine timing cover with rear main oil seal.
• Custom Teflon to Teflon aircraft grade front main oil seal.
• SCT X4 power flash programmer with a custom tune installed for the 6.3 displacement.

Remember this stroker process is on a 2004 Ford F-250 all stock! Now, if our stroker is installed in a 2005/2007 F series with the newer FICM, you would gain an additional 55 horses and torque would increase as well. Also the 05/07’s have a 3 inch exhaust which adds even more power.

So they tested a bone stock 6.0 with realistic dyno results, then tested a "bone stock" 6.3 stroker that gained "176hp" to the wheels.....oh yah it happened to have an SCT with a custom tune written for the 6.3 motor....but still bone stock.....and looky there stock HP levels for a tuned 6.0:doh:


Where is the gain???
PASS....Money can be better spent elsewhere...

Edit: also....I had no clue that 05-07 FICM's give the older trucks 55hp gains.....where has this info been for the last 10years????

 

What? They doubled their price to 12.5 for a short block??? They must have switched their target sales group from "hardworking everyday American" to "sponsored competition team"

 

That's how it looks to me. No mention of heads or long block in the quote so I assume the 12.5 is short block. Needless to say I am not considering it.

 

I plan in keeping my truck for literally ever. So if my engine gets 600k on it and i end up needing a new one and my frame is still straight, this could be an option for me. 12.5k verse a new truck.

I would like to see when all this new torque comes in to play, if its a lower rpm than with pur current curve

 

Might not have been the best answer, but at least they told you it was a short block

 

Yeah that's right about what mine put down at the VDP dyno day....at that point the only mod I had was the ported intake and was running the 1.5 Beta turbo kit.....and the Mild Panty Dropper tune for stock bolts

 

I would hate to deal with them for any kind of warranty claims... That response alone is enough for me to walk away. Apparently they aren't in any great need for new customers with responses like that.

 

My original quote of their email got cut off some by my phone, but it is not much better. Now that I am on my laptop, here is the whole response to my email asking if it was a short block, long block or turn key engine (the build sheet is what I copied into the earlier post):

"Russell,
please read in detail the build/stat sheet, it will in explain what comes with the engine.
It is a short block with extras. If your keeping it stock, i will discuss throwing in heads if yours are damaged. If your building it to extreme horsepower then your heads will be upgraded on your end.

hope that helps,

Jack Cammarata"

 

Id like an itemized bill, 12.5k what in the absolute hell.

So they have a donor motor? That they machine, then put these other parts they machine in it. Where the hell do they get 12.5k.

Edit : and it also sounds like they are pretty proud of the racket they have going on too. Dont ask them anything about it.

 

3k for parts, 3k for labor, and 6.5k for Bill Hewitt knowledge, and sealant......:look:

I like lamp...

 

So I know I am reviving this a little, but got to thinking about something as I just re-sealed a bed plate on a 6.0....

Taken straight from the article:

"Keith torques each crank-cradle bolt with 170 ft-lb. Unlike cylinder-head studs or other fasteners in the engine, there are no “steps” or increases for torque values."

Except there is a VERY SPECIFIC bed plate procedure and values that are very much stepped!!!

Step 1. Torque all bolts in sequence to 110lb/ft
Step 2. Torque all bolts in sequence to 130lb/ft
Step 3. Torque all bolts in sequence to 170lb/ft

More or less added this to the piston skirt hack job point.....I don't think I would ever use these guys for a motor. Might even use Ashville first...:wall:
