289/302 Ford V-8 enginee

Basil:

It looks like you had a little problem with the print around part of what looks to be the plug openings? Any ideas what happened there?

Don

Yep, that’s one area that is too thin and needs some CAD attention. I drew all parts in full scale. The model is right between 1/4 and 1/3rd. 2/7th? or 28.57% of full scale

incredibly nice work my son would love this as he is dyed in the wool Ford guy maybe slanted more toward Cleveland engines but a real Ford guy .

I’m more hemi Chrysler and race heminpersone . You can purchase virtually every part forvfacevhemi do others have done cad models . They would be easy to scale down for desk top printing but none have done this yet

But great work on your project

Gentlemen, I've gone just about as far as I can go on this 3d printed engine without making all kinds of tiny parts. The whole basic engine is there, with starter and alternator. I printed up a base and supports which bolts the engines motor mount bosses. I have been neglecting some of my other work so I can put this thing away for now. I have the crankshaft and camshaft installed in the engine also.

 

[ddmckee54]

Yeah Basil, a full sized thin wall gets real thin at that scale.

These 3D printed engines are really cool! I would like to make something like this for my brother. He has a '63 Chev SuperSport with a 409 engine ("four speed, dual-quad, positraction four-oh-nine") that he has owned since '69 or '70. Does anyone know where I could get detailed drawings of this engine?

Probably won't help much but the 409 is the same block as the 348

George, glad to see you made the leap to 3D modeling & 3D printing. There is no limit to your creations now!

Fantastic work George & Terry! I'm really looking forward to all this!

Good point. I believe most of the differences were mainly cosmetic such as the inputs. For example, I don't think the 348 came with a dual carb version, but that wouldn't be too hard get around. But as you indicate detail drawings of the 348 are probably also not available.

Thanks

Craig,
If you can find a copy of "Chevrolet by the Numbers" by Alan L. Colvin there are a number of copies of blueprints for various parts of the 348-409 engine family. He has a number of volumes covering different year spans. The 1960-1964 version would probably cover the ones you are looking for best.
Sorry if this is too far off topic for a 289/302 thread.

George's 3D prints sort of beg for some lost-PLA casting work.

Some good slurry, a long burnout in the kiln, a pour slightly on the hot side, and bingo, we have a V8 casting.

Well gentlemen I think this project has come to it's end. Without making all the little fittings etc the main parts are complete. I really got started on this project when Terry Mayhugh stated that his next project would be a Hi_Po 289 engine which predated the 302/5.0 engine. A lot of people have seen this printed version and some of them thought it needed a transmission so having all the model files for my Borg-Warner T5 that I built for my 302 engine I went into Solidworks and tweaked the model files to make them more printer friendly. While working on the print of the trans I decided to go a little overboard and make the gears for it. Solidworks has a toolbox where you plug in the numbers and it will spit out the desired gear. I first went to a site called the Engineer's Edge where they have a calculator for creating the numbers for the gears. You start off with the DP or Module then put in the number of teeth on the pinion and gear. Now you start adjusting the helix angle until you get the proper shaft centerline numbers. Sometimes this requires adjusting the tooth count so the helix angle stays within reason. (20-26 degrees) You then take those numbers into Solidworks and create the gears. After they were all printed out and assembled on their respective shafts they turned very nicely against one another at the proper shaft spacing.

Very nice George. Super impressed .
I’m doing a 26 hour print of my engine oil sump at the moment. What filament are you using?
Maybe because it is lighter in colour, slightly translucent? the end result looks smoother.

Hi Basil,
I came by my printer second hand and it doesn't print extremely smooth vertical surfaces. I have read and checked all the elements on the printer, wheels, lead screw etc. One suggestion was that the temperature of the hot end was varying but I'm not even going there. I use a good quality tough PLA and it works fine for my purposes. I have tried PTEG but it took more adjusting to get good prints. My background when I was working was a computer modeler in a pattern shop so I enjoy creating the models as much as the finished parts. I have a Creality CR 10 S V 2.

 

[Basil]

Thank you George, For me it’s a steep learning curve with Fusion. Half the battle at the moment is looking at the engine detail and wondering the best way to go about creating that detail with the tools within the program.
I am progressing and I figured drawing this engine, which I’m quite familiar with, is rewarding practice.
Your work is a great inspiration.

I wrestled with PETG also George, but I’m now getting prints that’re stronger and better than my PLA prints. I changed a few parameters such as bed temp, nozzle temp, fan speeds, and retraction speeds and distances and now they’re coming out beautifully. I even got rid of the dreaded “Elephant’s Foot” with a minor correction in CURA.

Beautiful work on your 289. I was 1/2 way through the purchase of an original Cobra roadster (so equipped), when I was smitten by a beautifully restored Austin Healey 3000 MKII at 1/3 the price. Of course this was back in 1972 when the Cobra was going for $4500 and the Austin Healey was only $1500…

If you decide to share your files of the 289, let me know price and file type. I’d love to have that engine and tranny on my shelf!

Once again, beautifully executed!

George:

If possible, I'd also like the files to the 289, I've always loved that engine. They are tough little things, seems like you aren't able to beat them to death with a stick.

Back in my younger and stupider days I started putting a 289 in a Datsun PL620 pickup. Then I saw a blown version of the pickup and I swore that mine wouldn't hit the streets again without a blower on it. I had a 10-bolt top loader 4-speed out of a big-block mustang just waiting to be used behind it. Then life got in the way... I still have that truck in storage, but not the 4-speed - that I sold. Now I think a V6 in the Datsun will be more than enough excitement.

I bought the visible kit version of the 289, and one of these days I'll actually assemble it. Looking at the parts on the sprue they're OK, but there's not too much detail.

You can't have too many of these little guys sitting around, can you?

Don

Well gentlemen I truly believe I'm finished with this printed engine. I told myself I wouldn't get caught up in the 3d print world but it seems like I did. This project just took on a life of it's own. Someone had mentioned to Terry Mayhugh about making Cobra rocker covers for the engine that he's building so I thought, "what the heck" with just a little time I modified the original model part. The final and finishing piece is the air cleaner housing. Going by pictures on the internet I scaled and drew up what I thought was a reasonable facsimile, made the model files and printed it out. The cover needed to be modified several times to get a good print. First I tried it one way with the outer surfaces down but that led to an unfinished looking surface after the support was removed. I then flipped it over and the lip around the edge got filled in with the support material and I couldn't get it out. I ended up changing the model to accommodate the printing process.
So as I said, it's done.

 

[GreenTwin]

This is a fantasticly over the top 3D print project.
Definitely pushing the boundaries way out on this build.

Way too cool is all I can say ! LOL.
Just goes to show what can be done with 3D modeling and 3D printing.
The 3D modeling/printing hobby has taken on a life of its own.

[Basil]

Amazing job George. Still amazes me that we can draw components up on the computer, 3D print and bolt them together as a somewhat accurate complete assembly.
Additive manufacturing of usable components for our hobby is definitely in the future! Just like with current hobby 3D printers the price of metal type printers will come down over time if the demand is there.

George:

Thanks for the files. I got to looking at the visible 289 kit again. It's 1/3 scale so I'm going to have to try scaling up some of the parts using my slicer and see how they work with that kit. Some of the parts that come with that visible 289 kit leave a LOT to be desired, your parts put theirs' to shame.
