My usual valve train assembly is lifters with engine upside down, then the cam. Gravity holds the lifters out of the way while inserting the cam. Roll the engine right way up. Then insert springs and then valves. Turn the cam to install the locks on the valves that are on the heel of the cam.

Awesome to see the mirror finish you acheive with modern machine tools, on a engine almost 100 years old. That old girl has never been so flat, square, and true in it's life.

I was 15 / 16 when I started Building Model A Engines back in the day, 1971 through 1981. When My Mentor "SCOTTY" Passed away. YOU MY MAN, I WISH You were around and had the Same Capabilities as we see here. I LOVE the Work you did here to Improve on the Model A Valve-train. That wudda Been Really Nice to do back in the Day. And YES, Adjusting those Valves is Fun. Nice Job JIM. Really Nice Work!! Really NICE!!! I'am 69 now and No longer have my A's, Miss em too. Last Engine I did was a Model "C" with the Big Crankshaft Journal's and Counter Balance. it was Back then. Keep it up Jim, the Hobby Need's your Expertise.

The good thing about the model a blocks is that you can put .120 over pistons in it. After the .120 pistons wear out you can put sleeves in all the holes and start back over from std.

You gave that engine another 100 years of service life. Fantastic work!!

I know you get comments about wanting to see the running engine, but I’m one of those that gets great satisfaction from the machining. If you’ve seen one engine run, you’ve seen them all. But a good job of machining is a work of art. And that art form has reached its pinnacle here on YouTube. The creative process is now performance art. And the skills required just gives the performance that much more impact. I love it when you say “half-thousandth”. Precision.
Thank you for these videos. Thank you for being a perfectionist.

The only problem with these videos are we never see the completed project.

Great work! Thanks for the great videos!

Why do i love watching this so much? Im such a motor nerd 😅

[littlebearish]

The machine work you've done to this block and head is vastly superior to what was originally done. They didn't have to be that great from the factory as there really isn't a lot of pressure trying to force its way out like there is on today's engines. Awesome work man. Henry would be proud

[peterhodgkins]

Excellent! It's been many years since I've ground valves... We ground the seats with stones back in the 1970s, although the "Quik-Way" cutter systems were emerging and were highly desirable. We didn't have any way to use a milling machine to cut the seats, but instead we cut them by hand with a T-Handle.

I built a lot of racing engines, and we'd cut some really narrow seats for those engines! It was great fun 45-50 years ago, but the stuff your shop has makes what we were doing look pretty crude! Love the channel!

[scottallpress]

That’s one lucky engine, I bet even now days not many get this kind of workmanship applied to them . I’m sure this will be around another century thanks to this incredible work

[jerrytjohnson]

I've only worked on 2 of this type engines (flat head) and both times it was a real chore with the valve stem spring retainers but knowing how much easier it is with an overhead valve engine my hat goes off to those old school mechanics

I mainly work on air cooled Porsche and BMW stuff. Watching this video is fascinating. I knew nothing about these engines. Very cool to see how these go together. Kroil is the bomb, btw. I could have a engine sitting underwater for 50 years and Kroil could get that freed up.

[TotesCray]

It's obvious you all take a ton of pride in your work, and having 2nd and 3rd generation (even if 2nd gen is just the janitor now, ha!) is amazing. Great job! I'd love to see some follow-ups if any of your customers would be willing to provide them. As satisfying as it is seeing it all decked and ready to go, even more so seeing it running after everything is done. Keep up the good work.

[Carstuff]

I can spend all day watching videos like this!

[mustangmustang]

Not sure what it is but there is something therapeutic about watching old warped surfaces come back to life. Love this stuff and full engine builds. Hope we get a chance to hear this engine run. 🍻👍🇦🇺

My father in law has a 1936 ford V8. Its beautiful. He has take this car from everything off the chassis, cleaned everything and repainted the chassis and more. He upgraded it from mechanical brakes to Hydraulic, and the engine is larger than the original. The previous owner had hot rodded it, so the larger engine was his idea. He was the 2nd owner of this car. Its been in a garage since he bought it. Im waiting till he gets it finished for my ride in this beautiful vehicle. The engine does need to be reworked like this one.

[julianwinn]

Loved this video. Shows how a true professional works.

[chloehennessey]

Wow that Kroil penetrated deep.
I’m sold. I’ll take 10 cans.

I run a cnc live tool lathe every day and I still enjoy watching this channel and how calming and knowledgable you are
