Engine Building Part 5: Camshafts

[@MTHFT]

I did not believe I could learn so much about engines in a day. This set of videos is just awesome.. Thanks.

[@PetesGarage]

If you learned that much today...imagine what you will learn tomorrow! Thank you!

[@Bonanzaking]

Imagine now during quarantine when there’s nothing to do but rebuild an engine for a classic car.

[@chrisburnsed6349]

Clearest explanation on this topic I have ever seen in 25 years of building. Nice

[@PetesGarage]

Thanks Chris

[@knighthawk7777]

Great videos My age is 77 and I have been building engines (mostly diesels)for almost 50 years . Learning a lot from these videos. Never to old to learn.

[@PetesGarage]

That is a great compliment....thank you my friend

[@johngiordano3981]

Peter, on this video you mentioned somebody poking at you for continuously reminding us of our material FM, my personal opinion I have been watching your videos and I thank you for all your knowledge and experience, you have taught me a lot in engine building I am a collision repair expert and mechanic, however I am NOT an expert in engine building, and you have taught me a lot and actually given me the confidence to build a motor, and I just wanted to say no matter who pokes at you keep up the good work because there are many people out here and I'm sure you know they appreciate it your end result speaks for itself and if your technique works don't fix it matter what anybody says and I thank you very much.

[@PetesGarage]

+John Giordano That is awesome John...thank you very much. I always say I've never had an engine fail because it's too clean. Newer engines are designed with clearances in microns and only allow for a couple molecules of oil through the bearings. One micro-fiber and you'll spin a bearing. I appreciate your comment...thank you my friend

[@app369]

Pete, just started the Engine Building Series. Thank you so much, I can't believe how detailed you are. So much knowledge.

[@PetesGarage]

Glad you like them!

[@iranmoz]

Just wanted to thank you for all the time you put into everyone of your videos. I'm learning a lot from every single one of your vids. Thanks again!

[@PetesGarage]

Thank you very much. I am making them with the hope of helping as much as I can.

[@jamesmeaders898]

So I've been watching all of your engine building videos from 1 to this one so far and I just wanted to say these are awesome. I've learned a lot about car engines and I really appreciate that you took time out to make these videos and to go into as much detail as you do. Thank you for all the knowledge you've shared. I hardly knew anything about engines and I feel like now I have a good basis to know how to ask somewhat detailed questions and to learn even further. I've always been interested in learning about this subject but never really knew where to start. I'm still unsure about what exactly the camshaft does or what "rockers" are, but you've provided a great foundation for someone who knew close to nothing to start understanding how engines work. Amazing videos, and I plan to watch the rest soon!

[@timberwood9864]

Hey mate this series has a life time of of experience and knowledge and for you to put all the time and energy into making these videos is greatly appreciated. Cheers

[@PetesGarage]

+OZ MAN Thanks OZ the Great and Powerful. I'm glad to help

[@stevelindsay3643]

Its been a few years since I tuned into Petes Garage. I'm glad I'm back. Petes knowledge is second to none when it comes to engines and mechanical things especially the automotive performance end of things. It's through Pete's experience we can all gain some crucial knowledge/insight of the entire W-5 of engine engineering components and their function, their performance and building an engine to be a bulletproof solid hunk of iron and aluminum. I'm a SBC V8 builder, gen one old school engine builder, naturally aspirated is my niche, and the 406 sbc is my baby. About 5 years ago I built my first all roller engine and the learning curve was tough. So much of what I knew would not work in a roller engine and had few people to ask. It was during that time I started watching videos to get the information in my head that I was somewhat confused about. You never stop learning something new every single day of your life, and the day you think you know it all is the day you should start over because you are only fooling yourself or feeding an ego. There is not one thing you can do to an engine during the building process that won't affect the outcome. Knowing those things is the key to success, and learning all those things is the hard part because everything changes as soon as you change one component to something different. Camshaft, cylinder heads, bore, and stroke is the backbone of any motor. If you want performance street or strip pay close attention to the specs you want to use to make it perform the way you want, and don't be afraid to ask questions. The only stupid question is the one you didn't ask.

[@PetesGarage]

Awesome comment! Thank you

[@stevelindsay3643]

@@PetesGarage Thank-You Pete. There are many inaccurate videos on engine building and geometry on youtube. You have taken the time to explain to the layperson real data, specs and consequences which I appreciate. Engine building is not something anyone should take for granted and I know that through trial and error very well. I've been watching some of the videos you have made, and only wish I had watched them 40 years ago when I was a teen thinking I knew it all. BUT there was no internet or even videos back in the day. The oil pan painting video about sandblasting media is one I take to heart having made that very mistake with the outcome of torn up rod bearings in less than 200 miles when I was 18. It was a punch in the head preparing for the Friday night drags at the Luskville Drag strip I'd been working toward all winter. luskvilledragway.com/lead%20news.htm That mistake cost me the year back to square one on a shoestring budget. It took some time to figure out what I did wrong, but when I did it was an insult to injury and never made that mistake again. A tiny little thing like a few grains of blasting media can ruin an engine in record time with little evidence left behind. Thanks, again Pete.

[@PetesGarage]

That's why I started making videos Steve. I remember those days with no internet and nobody would tell you anything, it was all a secret.

[@stevelindsay3643]

@@PetesGarage Ain't that the truth. It was the school of hard knocks and not the knocks you wanted to hear. It is absolutely amazing what the aftermarket performance industry has turned into. I ported my first set of Camel Hump heads at age 16. I had heard of it being done but never seen it. It was through that experience I was the go-to guy for Small Block Chevy Head Porting. I was so sick of it I never wanted to see another head again, BUT that was what was available back then. Aside from aftermarket cams, pistons intakes exhaust and dual point, distributors, there were few other options back yard mechanics had available to him or her to have the fastest car in town. There were always machine shops, but who could afford that. It was not cheap to get a block bored. The trick was to find the right block, 327, 283, 350, 400 with good heads, the rest was up to you. 441 heads were okay, but the big valve fuelie heads were the best then. WOW HAS THAT CHANGED SINCE THEN.?!?. Keep making videos Pete, they are great sources of information and really well done.

[@PetesGarage]

Thanks so much Steve

[@Liam-B]

This guy a real pro. This video series is very comprehensive, and very concise. Pete repeats himself occasionally, but not too much. I've learned more from this series than ever! Of course, I'm a total greenhorn so it's not like I know much to start with. I'm looking seriously at this info with the intent of tuning up a Suzuki Cappuccino with stock F6A 3-cylinder (factory ITB and turbo) to safely increase the HP from 64 to 100+, which is commonly done, so I know it can work reliably and safely. Being walked through a big ol' V8 build makes me pretty confident that I could do a dinky little I3 Suzi. Thanks a million Pete!

[@PetesGarage]

Thanks my friend, I'm sure you can do it

[@stevelindsay3643]

Thanks, Pete. That was one of the best crash courses in Camshaft operation I've seen yet. If anyone wanted to know how a cam works and why it's so important to get right this is the video to watch. Camshaft options are a difficult choice when building a modified engine. I build SBC V8's Currently building another 406. It's a street strip mainly strip build but has to get from, race track to race track under its own steam without having to change heads, etc. A camshaft can kill low-end torque when designed to run at a higher rpm, it can also rob you of vacuum, power brakes and other undesirable things you want on the street. Bigger is not always better, in fact, it rarely is for something you want to drive somewhere from point a to point b. Those can be hard lessons to learn, which I did without a mentor. Pete's video is a great way to get a really good understanding of what's going on and why. Thanks again Pete great video.

[@PetesGarage]

Awesome comment Steve! Thank you

[@rishabhkashyap619]

Its whole another level of satisfaction from knowing difference between camshaft and crankshaft. Seeing cross section of camlobe in books and ultimately a master explaining it live. Its such a massive help especially to students of Motor Vehicle Mechanic like me. Love from India.

[@PetesGarage]

Thank you my friend

[@gmoomaw]

Just want to say thank you for all your videos. I plan on building a motor and glad I chose your videos first before I start my first project! Thanks Peter

[@PetesGarage]

You are very welcome Graydon. I'm glad they help.

[@otonielaburtobermejo4774]

Thanks to your videos, I feel confident enough to rebuild my engine in a couple of months! You're awesome 👍

[@PetesGarage]

You can do it!

[@nathanbirney8663]

Just wanted to say thanks for doing these great videos. I've done a lot of research and reading about engines, but nothing compares to someone with experience taking the time out of their busy lives to share their knowledge!

[@PetesGarage]

Thank you Nathan...I'm just trying to help as much as possible

[@dcal3745]

i bought a TShirt just to show support and keep all your vids coming. These videos are priceless its a small commitment for the tons of valuable information received. thanks again Pete

[@PetesGarage]

Thank you very much....I don't sell many t-shirts

[@jeremycopsey5992]

Thanks for braking it down into better description as it was very helpful in understanding camshafts and lobes and lifts more better.

[@bmack7749]

Damn Pete, I knew I should have went to school. I like the way you explain everything. I can't even think of a question you wouldn't know. Keep em' coming! Thanks!

[@PetesGarage]

That's awesome! Thank you my friend

[@jansirkia3809]

Thanks for putting this excellent info piece together! I will need to watch several times though, to get all the facts inside my wee brain.

[@PetesGarage]

Glad to help Jan

[@barrycassaday]

Thanks, great vid. I have built several engines and this video made me realize how lucky I was for knowing so little and still having them run!

[@jonathanbosco8458]

Thanks Pete, excellent video as always, foreign material usually causes serious problems for small engines, first lesson, first hour of small engine repair class.

[@PetesGarage]

+jonathan bosco I'm always amazed at how some people make fun of me because of that. I do that to stress the importance of being clean and deliberate. I never had an engine fail from being too clean

[@jonathanbosco8458]

Thanks for the contact, one reason being like the easy way and the other reason jealous of you

David Mccown Thank you very much my friend

[@maurell-webb820]

Again you have provided a wealth of good info. There's a lot more to engine building than I thought, but for me, a hobbyist, it's great! My son and I are working on a Pontiac 350 and a Ford 302. I hope my son will latch on to the planning aspect of engine projects. Again I appreciate the fact that you have taken the time to provide such great detail and making it publicly available.

[@PetesGarage]

That is awesome! Enjoy the time with your son. Teach him the right way and he will...both of you...will enjoy it for a lifetime.

[@PetesGarage]

I am trying my best to make them helpful. Thank you very much for watching and your comment!

These videos series are amazing. Thank you so much for doing these

[@PetesGarage]

Thank you for watching

[@krabenaldt7605]

Great information. I believe I need to watch this numerous times. Interesting to hear how one thing affects another. My dad would tell me things as a kid (watching rebuild engines in our garage as a necessity to fix our family cars) and I would recognize "my dad said that too!" He would say everything is a compromise!

[@PetesGarage]

It take a few time to understand. You were lucky you got to watch your dad...that's the best way to learn.

[@dustinnicholas3625]

+ramasamy venkatraman Thank you my friend. I'm not sure about in the world...lol. I'm just trying to help where I can

[@tanmelons]

I watched ever video of this build and what really made this different from any other build video is the great detail you went into about how to keep everything clean such as when you did the Crankshaft you mentioned FM and how to make sure everything is clean and how to properly put everything in

[@PetesGarage]

I wanted to make sure it was as detailed as possible to help anyone at any level learn something. Thank you for watching my friend!

[@frankmaggio4328]

Thanks for making this video! I'm a 42 y.o. ER Nurse by profession and not a mechanic by any means. I bought a 97 RS Camaro project car for my girlfriend's 20 yr old son. I wanted him to have an "Old School Ride". It appeared to be a lemon. At least at first. The engine would vibrate the entire car, I thought it was the mounts. After dissecting, repairing what I can, tightening her up each time. The vibration never resolved. After more research we found Cylinder#1 has 135lb compression while others have 167-180lbs. So after everything the motor needs a rebuild. "The motor needs to come out". Now I am finding out even more info- cams. OMG they make the 3800 series ll sound mean as hell. Thanks for explaining this stuff to me. I look forward to my first rebuild, and I want to see the look on my gf's son's face when he heards this car when it's done.

[@PetesGarage]

Awesome Matthew! Never give up!

[@PetesGarage]

There are many questions I would need to ask about your engine. Your best bet would be to contact tech support at a cam manufacturer and they will help you choose a specific cam that is right for your application.

[@PetesGarage]

I have...but I work closely with the machine shop so fine tuning and machining can be done before I assemble. It saves money to plan if you can use stock parts. I would suspect most people guess and end up shorting themselves on the full potential of a cam.

[@nosmilo]

[@PetesGarage]

The cam has 4 deg ground in it so at TDC the valve events will happen sooner in the crank cycle. By moving the crank sprocket ahead 2 notches it adds another 4 deg, so at TDC for cylinder 1 the cam is 8 deg ahead of where it would normally be.

[@Tain950]

Wow amazing I picked up a lot of knowledge from this video thank you.

[@peterhart9872]

Before installing the timing chain, fit both gears and put a straight edge across both gears to see if they line up. I have found a couple of engines where the block casting was incorrect and the gears where out of alignment, (289,302 Windsor blocks). From what I can figure out, the original ford timing chain installed by Ford was more tolerant to this misalignment than the aftermarket double row timing chains. What happens is the camshaft gear develops a "wobble" and thus breaks off the alignment dowel pin in the end of the camshaft, when it does the crankshaft keeps spinning but the camshaft stays still, not good, for the pistons hit the open valves. Great videos, thanks, Peter :)

[@stvmassacre]

[@hammerhead19able]

Hey, I have all factory setup with miles at 160,000. So my question, I would like to rebuild with same setup, but would like to upgrade to next cam up from factory, and would like to see if you can give specs. on type of cams. I do a lot of hauling wood, hay, 4-wheeling, hauling a horse trailer and other stuff used for truck. It would help me greatly.

[@PetesGarage]

+Thor Hamm If you call any Cam manufacturers tech line the can help you select exactly what you need

[@PetesGarage]

There are two different types of variable valve timing. The one I described and one with a 2 stage cam. The 2 stage cam has 2 sets of lobes and a spring loaded RFF (rocker) that changes timing and valve opening, more like the VTEC you are referring to. It is being used with variable displacement systems to increase fuel economy.
