I Use Goodson. Great peeps but sure miss The walking library Dave M.
I'm an expert on this
You should provide an update when the truck hits the dyno to show what effect all the extra machining had for the engine.
Same although I assume not much would be gained till top end is hit and most the benefits would be from the upgraded valves and reliability from proper size and none damaged valves.
Wish I had the tools and or someone in the area who could touch up my engine but the 6g75 isn't really a well supported engine.
Man, i absolutely love the attention to detail and thoroughnes you display in all your jobs, makes me feel amazing knowing there are machinists like you out there
I’d like to see the flow numbers with that low lift mod done. I bet it’s crazy better.
It would be very cool to see before/after dyno/customer impression for this.
I'm definitely sending my 7.3 heads to yall.
FINALLY a decent seat on a diesel!! Great video as always. the typical sharp edges on a diesel drive me nuts
Always in awe of your professionism
Love your videos…because they have no BS, and just inform us non-machinists about what you do!
Good ol 7.3 Powerstroke.
I've been waiting for this build. Internationals best motor. Here we go.
Just Love this father & son operation!! Reminds me of the days when I learned from my dad in the shop/garage where he learned from his
Have been watching you for a while, and enjoy your work very much. However it's all way beyond my pay grade. Thanks for the videos.
I have been watching ur short Videos and now I am a Subscriber here. What Breath of Fresh air to see this type of work is still being done. I am Retired myself but again this is really a “Dying” Trade. Grant you some ppl think there is a Dime a dozen shops around that still do this but not a GOOD as ur shop. Most Machine shops today want Quantity instead of quality, You have chosen Quality. Great Job.
This northern Alberta boy loves the channel. As always, very interesting. I don't post anything lik this myself, but certainly enjoy watching it.
As an ex northern Alberta boy (Nampa) who moved down south (Brooks), I also love this channel.
@@ndog1234765 right on. Great channel hey? I understand the basics and pretty much everything they post, though I'm not a mechanic.
Nampa! I've hauled logs into the Boucher Bros. Sawmill.
Brooks: I know the smell of that town too! Hopefully you're upwind of the packing plant.
@lovesloudcars Only some days, haha. You get pretty used to it, sadly.
Great

Yep sending my heads to these guys so much detail I love it
I wish the machine shop I've used in the past would let me shadow them while they machine my block and heads... I would likely get in their way and annoy them when they want to just work... but would be awesome to see the work done. Thank you for filming and putting your content up! I can't get enough of this!!! I've always "known" what they do at the machine shops with my heads and blocks, but could not understand how they get a lot of those items done... Now I know how! You do amazing work and turns out looking GREAT! Lots of math and experience goes into this work. I've worked in construction and other mechanic work my entire life and I know there are those things where when trying to tell someone how tight or how to do something, you say, just feel for it to be right... There has got to be some of those scenarios with your setup where you get it lined up and ready and you just know how far the grinder "wants" to go and you really can't explain it, but just feel and know it from experience.
Fascinating!
awesome work
I have had 7.3 Fords since they came out and have never had head or valve issues.
Edit- lol I’m not pushing 550 horse either. Makes sense now.
Well done!
if / when i ever get around to my dream engine build of a 6.7L cummins with a P-pump, id love for you guys to do the machining on it. your attention to detail is awesome and i see that you actually care about your work. im a machinist as well but have never done engine machining work, ive always sent it out because of the special equipment needed... i hope that one day ill have some work for you... but untill then, ill continue watching your awesome videos! cant wait for the next one. BTW, i really like the high performance builds, they are fun to watch :)
I simply lover your work. 😄😄
Thanks for sharing 👍
decades ago my boss made one of the most power vw engines, one thing he had was a massive lift cam , and he machined the pistons to compensate. he was a mechanical engineer.
🤣
@@cwbuilds9215 it was quick for what it was 9 sec 1/4
Dont knock those 1200lb beetles. They dont take much power to make them pretty quick as well as the weight distribution really helps with traction when the powertrain is basically right over the drive wheels, pretty much the perfect drag car setup really.
Would be interested in knowing more !
Including an opportunity to speak with him about it !
One thing I am, is a VW PERFORMANCE nut !
Anything you could do, to give me the opportunity to speak with him, I would genuinely appreciate it !
I take VWs seriously. My first new car was a MKIV Jetta 1.8T.
I love the sounds and feels that German cars have, and a VW was the only way I could afford one.
I once worked on a microbus, and it amazed me that a car could be that simple.
Great video 👍🏻🇦🇺
Beautiful work!
Wonderful! I truly look forward to videos from your channel.
Nice work. I'll send you a pair this fall. ✌🍻
Would be so cool to see where these engines are ending up each time later down the road when they're built and running.
love the videos and the way you explain the whats and whys of your process
I have been waiting for a 7.3 video. Would love to see a complete rebuild.
Another great job!
Your attention to detail of work is awesome.
What a cracking video, shows you how much work that goes into a valve job.
Thanks guys, great vid
Great video. Your parents are great. I love how your dad has taught you a fantastic trade.
I think you have the cleaning guy confused with hus dad ... 🤪
The cleaning guy sure taught him well
Love the work and the level of precision and accuracy something I was not capable of in a tech school
Cool freeze-frame at 10:10
Yall guys do good work, that's hard to find nowadays!
Very enjoyable video... thank you
Thank you
Just wanted to add some Apples to Oranges discussion to the mix. I've done a lot of seat profile testing on the 7.3 IDI, including the BSS cutters you used, and they weren't effective at all (On the flow bench) The IDI has a completely different intake port and larger valve, I assume that's the reason for the difference. I'm still working on the exhaust side of things. Also, the pocket clearancing didn't make any difference... Again, just so I don't get yelled at, I'm talking about the IDI, not the power stroke here. These mods might very well make a difference on the PSD (I haven't tested them) I just didn't want people to assume they will on an IDI.
If you are building a high performance idi 7.3 you are for sure a dedicated hardcore guy! Awesome.
30 deg seat angle is favorable to low lift flow while 45,50,55 for your mid to high to the xtreames of pro stock. Every single port design will favor completely different seat angle. 5 angle isn't the end all be all and especially when you consider stock seat angles of every 15 deg. Every detail matters and changes things. Port design, port angle to the valve, port angle to the cylinder, valve angle to the cylinder, 2v,3v,4v,5v,valve head dia/bore, lift, lift/dia valve, curtain area, tumble, swirl, local port velocities, air velocities around the valve, port shape as in circular being most efficient, oval next and square or rectangular least, the circle having less surface area thus less frictional losses. Thats just some of it.
@@_FJB_ the biggest gains I've seen so far on an IDI head (again apples to oranges), on the intake, even more than doing any porting whatsoever, is widening the seat to .280" at 30*. This bumps overall flow 7-15cfm across the board from .100-.500. I havent gotten too deep into the exhaust side yet, but intend to do some exploring there. Every head is different, and IH did a pretty good job in stock form with the 6.9/7.3 IDI.
Not only would this relief tool help diesel heads, it would probably be great for the Chevy 348/409. It might also be good for the VW VR6 12V.
Looks like your valve seat install driver needs to be dressed. The hammer end looks to be mushroomed from use.
Loving the detailed content.
man! its like different language, sounds ULTIMATE
you guys perform alot of amazing work
Very detailed prfessional work
You have some top level tools. Very impressive.
Always so informative and fun to watch
Thanks for the detailed video work!
We all know "The Cleaning Guy" is your teacher!
Performance and 7.3 should never be in the same sentence together.
Play it now!
Very interesting ! Thanks for sharing !
I paid over $1300 to have my heads completely done at a shop called Klispies. I gave them a few good cores to chose from and preferred having them built vs buying "reman" heads.
When I got my two foot straight edge I probably was lucky. I found many humpback blocks, twisted and swayed. Was amazing.
I met Joe Mondelo when I went to school @ NTC Bemidji. He was the one that recommended me to the school when I was searching out schools over the phone.
For the love of spawl, grind off the mushroom on that seat driver. 😂
How much does a job like this run?
Thanks again great stuff
Excellent video! Nice job as always.
Serdi is an Italian pride, the factory is not far from my house. 🇮🇹🇮🇹🇮🇹🇮🇹 I love your videos
I had no idea they were Italian, I thought they were American
@@iaial0 it has offices both in USA, France, UK, etc. but I think the production is all in Italy, I think I'm not 100% sure
nice work
Now that is attention to detail. Well done. If I ever have 10k to throw at my 7.3 you're getting a call
Best engine ever built. Love mine... High performance is not a word I would've associated with 7.3 though lol
Letttttttssssss gooooooo!
JAMSI Online
550hp 7.3 wont be long for this world
Haven’t watched in a while. But this is a great video
Do you refer to one big master book with every engine spec known to man or do you have an engine specs book for each car maker? Are they available to the public?
awesome
Love that work
Great job
From argentina
Thanks for watching!
I think Joe Mondello is probably the most knowledgeable man in the business.
wish you all were closer you do pro work
CNC's have a mode where you can have them vary the spindle speed continuously to reduce chatter
its nice to see you are getting onto the performance area. Are you planning on measuring the CC combustion chambers?
Not really much point, there is very little chamber volume left in those heads - they're as flush to the head surface as you're going to get.
Wish I could see the finished product running and maybe even a dyno test
You guys do phenomenal work. I'm not sure how your pricing is, but I'm sure it competitive, especially considering the amount of shops that do what they did to his first heads.
A true professional consults with multiple piers and makes a balanced decision when they're not 100% sure of something. That's what I see here.
Would like to see some 2 stroke machining
I like it
Notification squad Have a nice weekend!🔥🔥🔥
I noticed that your valve seat driver tool has a mushroomed head from lots of productive use, and I'm concerned that a bit of that driver head could spall off next time you whack it hard and injure you or the cleaning guy (or anyone else standing nearby). Maybe run it by a grinder and eliminate that mushroomed head? I want to keep you guys healthy so you can keep making more videos for me to watch!
Question on cutting the relief. Doesn't that create a hot spot where the two reliefs Siamese into each other? I would think you'd want a fillet in that area to reduce the chances of that.
I too would like to know about this. I know that 7.3 heads can crack in that space between the valves in stock form, does the sharp peak make for too much of a stress riser?
I’m a little surprised considering I’ve been running a stock bottom end stock head with a set of cheap aftermarket valve springs for 8 years would definitely be interested in all the part number for the valves and tooling for my future billet rod engine
Would you guys be able to do work in the older 7.3 IDI heads and block too? I have one I need done.
Great video 👍
Hi!
❤❤
That serdi machine is so fuckin cool
wow, diesel sure is a pain! I guess its the price you pay for burning liquid coal...nice work as usual!
👌👍
Curious if you guys have ever done a mild port job maybe just to clean up factory casting. Would it moderately improve flow? Looking for a simple way for a stage 1.5 ish build to breath a little easier for efficiency purposes.
Do you guys ever do 5 angle valve jobs? Why, or why not?
This is a "5 angle valve job" if you read the specs on the cutter that was shown on the screen.
Fuking awesome
TY 7.3 All Out Head Nice
Ray I do have to ask why don't you use wash tank to clean transmission cover to clean both sides?
Did you try differing lubricants when cutting the seats? (Kerosene etc)
I have a few extra set of 7.3 L heads, I was wondering what it would cost to have you go through a set as you did in this video. I will be running around 6-650 hp and already have stage 2 valve springs, retainers and shims.......thank you
