Kirkham Motorsports University CNC Billet Aluminum 427 FE Engine Block 1 of 3

Here is another KZbin from Kirkham Motorsports University. Here we show you how we took a solid, 386 pound block of aluminum and machined it into a 427 FE engine block. www.KirkhamMotorsports.com

As a machinist who has done large complex parts, I can tell you, this stuff ain't easy. The opportunity for mistake, or error is extremely vast. And 1 simple thing, at the end of the entire ordeal can totally screw up everything.

[@scottym3]

I could watch you do this all day long. I'm a retired CNC Machinist living in the Space Coast of Florida. Many of my parts went up in space for satellites and such. I do miss working on them. Ran quite a few Haas and others. I so loved setting them up and getting a first piece off to see what the final product looked like. Great work on those blocks.

[@KirkhamMotorsports1]

Thanks! I love making things! We are working on a crazy part right now. I'll work on getting a video of it up for everyone to see. It is 80 inches long!

[@hockeymann88]

Good Lord. That engine is at least as desirable as the car. Machined from a single billet! Holy hell man. That must be the sweetest FE on the planet.

[@KirkhamMotorsports1]

Thanks :)

[@KirkhamMotorsports1]

It really is a ton of fun. There is a huge need in US industry for guys who can design, program, and run these types of machines. Keep working hard :)

[@tunaharhar5666]

As an ex machinist and tool crib/tool ordering person I can appreciate the work you are doing! You were hanging some of those endmills way out there which tend to snap (Goodbye $3-400 each). Great design and programming!

[@KirkhamMotorsports1]

We sent the block out to be line bored at an engine shop. The cam bearings are all the same size. We took out material to save weight (it is easier than going on a diet :) We are using 6061. It is the best all around alloy for this application (corrosion resistance, strength at temperature, availability, etc).

[@rossbmarvin3rd]

I spent the majority of my career as a CNC set up man. That's really a great job you've done.

[@ghost2coast296]

Wow you really pushed that machine to its limits. I would have never imagined an engine block being made in a machine of that size

[@NinthDensity]

Beautiful piece of work. Have never heard of a whole block being carved out of a single billet.

[@InTheDogHouse3DPrinting]

I have always wanted to work in a shop like this. I don't know anything about machining, but I would love to do assembly work in a place like this. I have been a mechanic for several years, and I used to build engines from kits, and rebuild engines for lots of customers. Now I work on motorcycles and ATV's, along with small engines. LOVE being a mechanic.

[@mikldude9376]

Nice work , and you are a gentleman David, you answered all those questions , even the smart ass ones with complete aplomb, well done all around sir !

[@KirkhamMotorsports1]

Thanks :) Most people really do want to add to the discussion. I certainly don't know everything and have learned quite a bit listening to other people with more experience that I have. Thanks for the kind words :)

[@KirkhamMotorsports1]

Great question. Cast iron sleeves have been used for decades in engines. Cast iron holds oil well and wears for a long, long time. There are some exotic sleeves today that are used as well-- such as Nikisil.

[@jlo13800]

[@m98custom1212]

This why I love working in machining watching a billet turn into something useful. Amazes me every time

[@KirkhamMotorsports1]

We have always wanted a horizontal. It certainly would be better for a block. That is a great idea to use the lathe for relieving end mills. We will get an insert and try it. We used the mill this time because we had it handy and were back up and running again in about 15 minutes. Great suggestion :) Thanks!

[@henryross4343]

I have always wanted to own a Kirkham SC 427 - your cars are freaking beautiful. And then when i heard that you were going to start machining your own 427 aluminum blocks and just thought these guys are serious motor heads. I may not own one, but i appreciate your interpretation of Shelby era of cars!

[@KirkhamMotorsports1]

Great answer. There are other exotic steels that have been used over the years. Cast iron is the best combination of wear, cost, function, ease of manufacture, lots of experience, etc.

[@KirkhamMotorsports1]

Thanks! There are lots of smart people out there. We are fortunate to know many of them who have helped with a lot of great ideas!

[@OmaarHL]

A masterpiece! We used to joke about this.....it's incredible to see these. Keep up the good work.

[@CruzDemon]

A work of art! I look forward to seeing more form you guys...

[@atowngreen]

Very very impressive! I love the fact that you guys' use HAAS's -many people believe that they're just cheap, throw-away machines; when they're easily capable of achieving tolerances within tenths. I can't imagine how long it took to program and plan something like this. Most aerospace parts I've programmed/made don't even touch this. Kudos!

[@dietermeyer9231]

You don't repair a HAAS, you replace it.

[@KirkhamMotorsports1]

With billet you can make what ever you want and you are not stuck with a casting. With a casting you can cast hollow areas with cores. Castings are generally weaker--especially at working temperature. Billet lets you be really creative. We have lots of Haas equipment. We just bought a huge GR-712 and we love it.

[@joshssauce]

I would LOVE to do this one day. I'm studying to become an engineer and I love this stuff haha I can even get emotional about it

[@jlo13800]

yes i got 4 1600oz steppers for my 2 stroke big block project, i might need 5 axis not sure as i have to run a baffled sealed airtight crankcase for scavenging. most 427 can un dirested oil injection and are popper valved 2 stroks with 2 VRP pumps. Most today can run XD-100 ETEC BRP 2 stroke oil with out problems ans most 572 CID 2 stroks do anyways. I might get bigger 4200 ounch in stepper motors with drives and board for more handleing for the big 2 stroke!

[@KirkhamMotorsports1]

[@KirkhamMotorsports1]

@fixerdave, Great question! We rough machine the block and leave lots of material on for a "roughing finish pass." Then we machine the block again and leave about 0.010" for a finish pass. Then we do the final pass. Because the block is free to rotate on the pillow block end of the "A" axis, it twists and stress relieves every time the pillow block brake releases and the block rotates. We connected the pillow block brake to the same air brake that is used on the rotary axis.

[@KirkhamMotorsports1]

That truly is a work of art, the stuff of dreams, and job well done! I can only imagine what it took to get to this stage of manufacturing and the time and start up costs must have been steep, but as the old saying goes, fortune favors the bold. Simply amazing and great video!

[@jlo13800]

Thats a way to make a BB 2 stroke. i got a few 1600 oz spepper and might need bigger but the 1600oz in stepper should handle a big block od aluminum for a BB 2 stroke ove about 600 CID. it needs bafled crankcases and mor bore spacing, this 427 is a poppet valved 2 stroke with direct oil injection though that is show here.

[@TheRandomActivity]

CNC milling machines are amazing!

[@ArnoldsDesign]

Yep, sometimes you have to use things on hand to get the job done. I've relieved endmills now and again using a harig on a surface grinder. This looks like a cool shop to work at.

[@MrMojaveDude]

Very Nice, Having been a CNC machinist almost 30 years, I have many questions, But, I rather just give Props for job well done, Thanks for the Vid!

[@KirkhamMotorsports1]

Yes, all material moves and stress relieves as you machine it. We roughed everything out and left substantial material all over so it could stress relieve. We then did 2 finishing passes.

[@NintendoFunTime]

Not sure off the top of my head if that machine is capable of running through spindle coolant, but if it is, you could save a lot of time and money when drilling the oil and water journals if you used a through spindle carbide drill. Guhring makes some very nice ones. Pricey, but they drill fast with no pecking, and they last quite awhile.

[@gheumann]

As a gearhead and amateur CNC home machinist... DAMN! Nice work!

[@darrylhorrocks5688]

[@OriginalBrett610]

Thank you so much for this video! It was amazing to watch!

[@huskerpwrful]

How many end mills do you go through in one block? This is pretty impressive and it is good to see this type of manufacturing right here in the US. I am a mold toolmaker for a company and it kills me to see foreign tools come in. More people need to be aware of what we can do as machinist. It is also good to see you using an American Made machine! its so easy to get others in this world. GREAT VIDEO!

[@KirkhamMotorsports1]

@dethmetalderique GREAT question! 7075 is a great alloy for high strength--at certain temperatures. However, 7075 has poor strength at the higher temperatures encountered in an engine. 6061 is actually stronger at engine temperatures. 7075 also exhibits very poor corrosion resistance. 7075 is also very susceptible to stress corrosion cracking. 6061 has far higher resistance to corrosion.

[@KirkhamMotorsports1]

Thank you for your kind words. The block indeed DOES distort all over the place as the aluminum stress relieves. We have to rough it with about 0.065" of material all over, then do a pre-finish pass and leave 0.010" before we final finish machine the block. I think the entire process was 25-30 hours.

[@ArnoldsDesign]

Nice engine block. I like these Haas machines. I would recommend using diamond wheels for relieving endmills instead of CBN. The diamond wheels last a lot longer and cut faster and easier.

[@lobomella128]

This video is 13 years old as I type this; considering how fast technology moves, what is the biggest engine you can make these days in 2024? How fast can it be done? This is truly impressive, even after all these years.

[@KirkhamMotorsports1]

You can make an engine about any size you want. CNC mills can be very large. Speed depends on detail and size. The bigger something is the longer it takes. The more detailed something is the longer it takes. It is truly amazing what these machine do.

[@PhaseConverterampV]

I run the same machine. However, your parts are considerably more complex. Excellent machine work. Thanks for posting video. A day and a half cycle time?

[@KirkhamMotorsports1]

Yes, I think it was about 30 hours of machine time.

[@KirkhamMotorsports1]

@xevious2501 Thanks. Yes, all the chips are recycled. It takes much less energy to remelt chips than to make aluminum from oxide. I don't know of anyone who machines at extreme temperatures. I am not sure how you would keep the part at any extreme temperature for any meaningful length of time as the machining process is quite long. We take thermal expansion into consideration when machining tolerances. I am excited to look into any info you might have on Ferrari's process.

[@KirkhamMotorsports1]

Good questions! We bored the camshaft 1/2 way from both ends with the same size bores. Many variables are taken into account when making a block--yield, stiffness, etc. The strength of 7075 falls off quickly at the operating temperature of the block. The block dyno'd at 630 hp. It has 4000 miles on it and two track days where it ran for almost 6 hours straight each time. No one was kind to the motor on the track. Thanks for asking. Happy to answer any questions :)

[@KirkhamMotorsports1]

Yes, tools wear out. We regularly inspect and replace them. We really don't adjust tool paths to compensate for tool wear. (However, there is slight adjustment in a lathe for tool wear when making parts with high tolerances).

[@moonryder203]

Awesome! Working on engines like that must be exciting! plus nerve recking for both programmer and set-up guy! LOL!! You definitely have some talent in your shop! Good luck on all your projects! Thank you for sharing this video!

[@njfinests]

whats the advantage of using sleeves vs. (block) walls for the pistons? Damn that block looks thin as hell. How much Hp & tq can you run through that 427 block & be reliable?

[@KirkhamMotorsports1]

With the sleeves we can make it lighter. The engine dyno'd at 645 hp (if I remember right) and it now has over 10,000 miles on it.

[@njfinests]

@@KirkhamMotorsports1 hey Dave, Whats the maximum amount of HP & TQ can a person get when he orders one of your kit cars?

[@KirkhamMotorsports1]

@irainco, Great question. Billet aluminum is very strong and resistant to softening at the temperatures encountered in a running engine. Also, with a block of aluminum, we don't have to make a foundry pattern and wait for a foundry to cast the block--only to have to machine it later anyway. We can test the design and make changes quite easily and we are not locked into a casting pattern. This works very well for short runs of parts.

[@michaelovitch]

it's just a metal properties problem. for ex : there are bearings (soft alloy) sandwiched between very hard steel parts to avoid seizure.

[@KirkhamMotorsports1]

There are advantages to castings and advantages to forgings. Forgings are stronger and have much better strength at operating temperature. Castings let you make hollow parts (water jackets, etc). We solved the water jacket problem by using wet sleeves. Castings also have serious porosity, core-shift, and inclusion problems.

[@KirkhamMotorsports1]

Yes, I posted we could make a car in Stainless--but for some reason I can't find it right now. There are problems with posting comments now that youtube and google and google+ are connected. They just started. Hopefully they will have it solved quickly. And...thank you very much for the kind words :)

[@KirkhamMotorsports1]

Thanks for the vote of confidence. We are completely booked right now with orders.

[@KirkhamMotorsports1]

@PixMan107, Indeed those drill bits are very fast...but extremely expensive. We have "through the tool coolant" on the mill (you can see it when we do the deep milling on the mains side). That said, "speed" isn't always paramount in a machining operation. When a part runs all night long on a mill it really doesn't matter if it finishes at 3:00 am or 4:00 am.

[@keithlane4343]

I'm a CNC programmer / set-up / production manager, have to ask, what's the total cycle time? We've been machining prototype parts from scratch for everything from ROV submarines to cutting edge medical components, and I still like to see a part emerge from a solid block of stock. Still not jaded after doing this for over thirty years. Enjoy seeing your videos. Take care

[@CarlJohnson-km8zr]

that's amazing, I've alway's been a fan of the 302 ford, and always wanted to mill a forged aluminum block and somehow mill a 4 valve head based off a Honda crf unicam design...but now ford has the coyote... Its amazing that japan and other countries used overhead cam multiple valves per cylinder to boost reliability and performance to different applications over the years and now the us automakers are utilizing it.

[@KirkhamMotorsports1]

We haven't made billet heads yet. We are seriously considering it, however. We determined the seal relief by looking at Parker Hannifin's O-ring charts and looking at other sleeved motors. I don't have a video of the motor running...I should get one. We have just been too tied up around here with other cool projects :)

[@KirkhamMotorsports1]

Indeed the original 427 FE block was cast from iron (although there was a 390 block that was cast in aluminum for CSX3002 back in the day). Currently, Shelby uses 6 bolts in their cross bolt mains (two more than original) and Pond uses the original two bolts in their cross bolt mains. We decided to use a girdle (like F1 engines) for our block. All four of these aluminum blocks use sleeves. We have thought about using nikasil, however :)

[@holdernewtshesrearin5471]

saw the name and had to watch.im also a machinist although i no longer work in the field.wild! great vid btw!

[@KirkhamMotorsports1]

Thanks!

[@KirkhamMotorsports1]

Thanks for some great comments. The block dyno'd at something like 630 horse power. It has run several track days going all out--all day--with no problems. Many blocks have water between the sleeves (F1 blocks are made like this). Like most things, there are advantages and disadvantages to blocks with siamesed bores and blocks with water around the bores. We chose to have wet sleeves to improve the cooling (a problem in FE motors). Thanks!

[@xevious2501]

Very nice post. My question is what happens to all the billet shreds? im guessing it can be melted down and re-used. Also, isnt it important to machine blocks under extreme temporatures. in other words, whatever you machine out at room temporature will not keep the same exacting dimensions under operating temp. so usually you would Freeze the block condensing it while CCN'ing so that the block will expand to that exacting size under operating temp. Its how ferrari makes there blocks.

[@KirkhamMotorsports1]

Great question :) Yes, the shavings are absolutely recycled. It is very efficient to recycle aluminum chips. The dies are VERY expensive to forge a block closer to the final shape. This is a simple way to test out a new idea.

[@tashpaug]

That is a real work of art!

[@timorgano]

Good to see that the chips are recycled. I've always wondered that after seeing videos from dart and other people. They never say. What is the maximum sleeved bore of these blocks?

[@DougHanchard]

Wow... just ... drool.. Questions: Did you CNC build your own 427 FE Heads? If so, which model did you decide to go with? Tunnel, Low, Med or High riser? What kind of fuel system did you decide to go with? Weber, Injected or.. You show how you made seal relief's at the bottom of the sleeve's, what material are the seals made of and how did you determine what gaps to to machine to, given expansion needs and machining tolerance with forged 6061? Any video of the engine complete as an assembly?

[@KirkhamMotorsports1]

Yes, we could certainly do it. The issue is time. We just have so many projects going on right now we can't get to all the cool stuff we want to :)

[@TrainDriverRob]

A very impressive and very expensive way of making a block. The finished article is a work of art and I'm amazed that it doesn't distort during and after the machining. Out of interest what is the total cycle time for this?

[@TPVPRO]

That's impressive I'm guessing you guys can make a complete engine right from the CNC machine.

[@KirkhamMotorsports1]

We probably could. I have thought about it.

[@KirkhamMotorsports1]

@rajgd009, We don't know how much power it will produce yet. Our cars generally have 600-700 horsepower. They really don't "need" any more than that. We haven't done anything to reduce the internal stresses except for careful machining practices. We can't wait to see it on the dyno.

[@nukl466]

Hope the motor goes into the car that was behind him, Holy Cow that thing looked beautiful.

[@KirkhamMotorsports1]

Yes, we are quite sure the block was forged. We bought it from an aerospace forging house in California that supplies to Boeing.

[@a6t8vw1]

Impressive for a HAAS machine. good work

[@oldmusher]

Guess I have to agree with Mango. I understand that this would call for a bigger billet, etc. But the advantage an FE still has over (say) a 460 type block is the skirts. I know...it isn't a cast block, and that complicates making a skirt area. Considering this isn't "vintage", and what it must cost, I'd consider an aluminum Windsor 427 less expensive, but still competitive. It is a total work of art, though. What main caps does it use? Or are those billet as well?

[@KirkhamMotorsports1]

@522design We can do a block every couple of days if we wanted to. However, we just got the first block back from the dyno and we are now about to test it in a car. We'll keep you updated.

[@trex1943]

wet sleeves, the block doesn't have a traditional water jacket, rather the sleeves are relieved to allow room for a water jacket once the sleeves are pressed in. hence the reason for the o-rings that were mentioned.

[@Mechknight73]

Are you able to have the "waste" material from machining recycled? After making about 3 blocks, you'd have about enough material, if you could collect it all, to make one new solid block of aluminium. Very well done, considering how much an old fashioned cast iron Boss 427 block weighs, that's a huge improvement.

[@KirkhamMotorsports1]

Yes, we recycle all the chips.

[@flyingdog1498]

Did you do a FEA on the aluminum block and a fatigue analysis on the high stress areas or just copy a cast iron design? 1982 Oldsmobile 350 Diesel comes to mind.

[@billwelter4101]

So you must have plates bolted on the sides for a water jacket. Also, what keeps the two sides of the cylinder walls from spreading? The head bolted on?

[@KirkhamMotorsports1]

@GNRacer, the block is based on Darton's MID system. The deck is open, like modern engines.

[@hayeslincoln3111]

Dave, My uncles worked for Allis Chambers back in the 50s. I think they'd be flat out amazed at how far we've come in technologies. It blows my mind to see how precise machining has come. It's so cool. Did you get my inquiry about building me a Stainless Steel Cobra?

[@michaelovitch]

The main problem is wear,directly caused by the materials properties. The coeficient of friction is very important. You cannot make parts to work together if the different material do not "marry" correctly. aluminum and cast iron work very good together,stainless steel is very bad : it will cause seizure,even with a very good lubricant. bronze is too soft,specific steel is good too with aluminium,but less than cast iron. all is question of metals qualities and own properties.
