I’ve watched many videos on how to degree a cam and this video has got to be the most comprehensive explanation. Other videos broadly go over the topic and some are so vague you wonder why you even watched it. By far the best video! TY!
Please never stop doing these videos for us. I rebuilt my sbc just with watching all of your sbc rebuilt, cleaning & stuff videos. Runs like a charm since 05/2018. Thank you for your videos and sharing all your knowledge with us!
This video really helped me. Most cam degreeing videos are very vague and don’t describe in exact detail the ins and outs of everything. Thank you. Subscribed!
Even English isn't my native, I can almost totally get a ton out of this tutorial, and this has got to be the best, most direct and obvious cam instruction on YT!
The clarity with which you explain what you are doing, how to do it and why is second to none here on YT, at least that i have seen. It is really awesome.
It was still a great video for cams !!!!!! When you exhaust the info on cams, move on to springs and what is needed to be known about them to select the right ones !!!!! Thanks for all you provide for us !!!!!!!
You might be able to export just the audio from your editing software, then upload that audio file on TH-cam to replace the one in this video. This saves you from uploaded the same video twice.
Had you for engines class at UTI in 2014 and learned 10x more in your class than the 3 others I have taken throughout my schooling! Thanks for letting us pick your brain and showing the correct way to do things! I'll be staying tuned in with you to see what crazy builds your doing!
Hi I just wanted to say you are THE BEST on TH-cam. Your cam video was so useful and so are your others. Thank you so much. I’m 23 and building a Chevelle, it’s nice to have these videos available for help without having to ask questions old times may think are stupid.
My first cam install was a Triumph 650, in the 1970s. Separate intake and exhaust, new cams to replace badly worn originals [no hardening]. After messing with degree wheels for a couple of days I called Norris... they opined that maybe they hadn't ground those cams to spec after all, but 'it should work if you time the exhaust to the intake spec'. It never ran right... now new hardened stock cams are going in the old girl, and this video will be a big help.
I build my engine just looking at your channel. You're so detail in what you do it's easy to follow much appreciated. I'm getting ready to rebuild my 5.7 Gen3 hemi .030 overbore. Using your channel will help me out alot
@@Myvintageiron7512 looking for to it. I was wondering what cam to put in it and clarify it for me I'm doing a daily driver but thinking of porting the ports of the heads in increase the flow as of now I'm using the stock 5.7 eagle heads
Very good explanation , I put the ramjet cam in my 350 vortec , just keeping my fingers crossed that it is ok .I have never degreed a cam .Thanks for the video .
Great stuff. I had a Pontiac 400 built years ago and the builder must have put a much larger cam than what he thought it was. When I started having issues, I put a degree wheel on it and found that it was 236/244 @ .050 110 .560 lift. All with stock 6x-4 heads and springs!!! No wonder I found crushed valve stems seal rings ... in the top of the head.
Killer vid mate! It's great to see a proper grassroots bloke simplifying and making easy for others to understand the complexities of how stuff works! You got a fan here mate, look forward to more of your content 💪😎👌
Wish you would have been my teacher in the late 70's when I was in Ag. Mechanic's school, They taught us how to find true TDC using a piston stop instead of the dial indicator method, not saying it's better just easier.😁 This is a very informational video that I'm sure will help alot of people, especially the younger generation. 👍
I really appreciate all your videos you are Excellent you explain well and always easy to understand, I play in High performance but in an amateur way and whenever I am not 100% sure I go see your videos. So right now going to degree my 580 cid 720hp 760 hp with the old Kinetic cam to see if any grinder could improve it. Thanks again and please keep doing your awesome videos!
Thanks again for your good video. I do my first cam degreeing now on my FE 390 by using this video. So everything is perfekt with my cam. I do a very stock rebuilt, except I use a roller cam and roller rocker. I ordered the cam and rockers from Brent Lykins. He helped me with a cam profile and other parts I will need for my rebuilt.
If you don't mind ( I can't imagine that you would but feel I need to ask) I'd like to refer to you on my channel. I'm documenting my first real build and I stress to both of my viewers ;-) that my channel is NOT a how to channel. Your channel is my go to for how to information and has been instrumental in me having the confidence to build an engine. I've know a lot of people with knowledge of a subject but who were unable to teach others. You are a great teacher. Thank You.
Absolutely best explained video out of the 10 I watched! So degreeing the cam is really just to double check the manufacturer to be sure they sent you the right cam, and fine tune if you have a really higher performance engine?
Thanks for all your effort in making this video. I am trying to find out what cam is in this car. I have no cam card, so while I have it apart I want to make sure that is best suited for the street.
I always double check this on the companion cylinder as well. These days I have seen some flat tappet cams be way off on the grind cylinder to cylinder.
Great video! off topic, but I see you have installed head studs on that engine. I did the same on my BBC gen 4 this winter. Used thread tappet on all threads, cleaned everything. Installed the head studs with ARP thread sealer. Almost everyone leaked coolent out. What do you use or do to get them sealed up? I see theres alot of forum thread of people struggling with this. Could be a good video topic aswell.
They never show any of this on the TV shows when they replace the stock cam in an engine. I know it's time consuming, but it should at least be mentioned. Great video.
I do have one question however. At around 12 minutes we were able to confirm that we have the right cam since the intake lobe was 420 thousandths AFTER multiplying by rocker ratio. Does this mean that the type of cam we have dictates our rocker ratio?
Excellent video. I don’t have a dial indicator lifter. Can I convert a hydraulic lifter to solid by removing spring and shimming with washers just for measuring purposes?
Hi! Thanks, I'm trying to understand this procedure and all of the details that go into a cam, and its installation. Your videos are the most comprehensive, clear, and easy to understand that I've come across. I'm about to rebuild my Ford 400, from the bottom up. I am fairly new to this, and this is the one step in the process that's a bit intimidating. One question, do you want to be able to check for piston to valve clearance so there's no chance of these two components contacting each other during first startup? I guess it worries me a bit putting a new cam in that will have slightly more lift, after the block deck has been machined down, as well as the head surface. I'll keep watching your videos to learn more! Thanks again.
Love your vids, thx quick question.. if I put Vortec heads on a 1988 GM 350 which length pushrods do i use? from the vortec engine that i yanked the heads off, or my original TBI GM block? thanks
I watched a video on here where the man installed the timing set on a dodge engine on the exhaust stroke. Is this correct for dodge engines? Never seen this before. I have all way installed the timing set on all engines on the compression stroke TDC and had no problems.
I'm a little bit confused. At 10:53 you find the intake lobe max lift. This happens to be about 122° on your degree wheel. Then, at around 13:00, when you explain finding intake centerline, you move 50 thou on each side of that. You end up with 109.5°. In theory, isn't that redundant since the degrees at max lobe lift IS the intake centerline? Am I missing something? And why didn't it come out to 122°, where the max lobe lift was? Not criticizing, I love all your videos. I have learned so much from you. Just trying to understand.
I use the inner base circle method of calculating lobe center an get a lobe center of 112.5 deg (22+67+180/2 - intake opening 22 = 112.5) from your number when measuring duration. why are your numbers different than mine?
I have a 1969 351 Windsor built by someone else. I don’t have any part of the build in writing (I don’t know what cam is in the engine) I really hate to pull the heads to pull the cam so this information should help me determine lots of information on lift duration etc. I’m trying to make decisions on intake manifold carburetor etc. thank you very much you are awesome!!!! should you work for University? lol
So overall the main point of “timing” a cam is really just to verify the Cam specs? I want to venture into my first engine build soon and trying to understand all the little details. This step seems to be just a verification step only? Like if the Cam was out of time, but also was the correct Cam, how the heck do you adjust / re-time the Cam to make it correct? Or you don’t? If the Cam isn’t in spec, you stop here and get a new in spec cam? I guess to me I’m confusing “timing” a Cam with timing an engine on like the ignition advancement or delay of spark. Like when you tune you can add a degree of timing so maybe I’m just confusing myself with the word “timing” here and it’s really “verifying Cam specs” not timing it?
You can do it with your heads on just gotta use the rocker arm for your lifts and through the spark plug bore for tdc and yes you need to once you swap your cam.
I loved this video, thanks so much for making great content. Also for making educational videos fun. It's not just theory your really doing it live and proving it at the same time😁👍👍 I am working on an OHC Ford engine right now and I liked what you said about retarding vs advancing the cam timing by a couple of degrees. If my engine could use a little more low end torque can I advance the cam a couple of degrees to give me a slight improvement on the low end torque? Let me know your thoughts on this because the cam drive gears are not keyed to the cam so I have a little freedom there.😉
Sadly from 2030 on all combustion cars including classics will be banned from public streets in entire EU and Scandinavia :-( In Germany the Green Peoples Party gave order to shorten fuel supply from 2025 on by reducing all conventional fuel stations to only one state operated central gas station per city or county. Now they want to slow down all the gas station fuel pumps from 20 litre per minute to 2 litre per minute...From 2027 on in the EU certain car spare parts will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning cars any longer....They even created a new kind of crime here, called emissions and smoke crime. :-(((
I am working on a 5.7 Vortec that I have installed a Comp Cam OEM type roller. 276/282, Lift .503/.510 with a 112 lobe center. The cam card calls for it to be installed at 110 degrees. With the timing chain point to point it shows 110 on the wheel. However the engine is a dog..... Comp Cams says the cam was ground with 2 degrees advance. Any help would be appreciated.

so degreeing the cam is necessary too when replacing an OE camsaft not only when building an engine, as you said the cams can be boxed incorrectly?
Great video! It now makes sense! Thank you!
Glad it helped!

Lock tight not to keep them from coming loose it works great for sealing bolt holes that go to water jackets
Myvintageiron7512 thanks, what kind og loctite? Theres like propaply more than 50 types
Im learning this at sam tech in Houston this is very well explained
Best video for us newbies finally can see the wheel in the video
Thank you
Glad it was helpful!
Question , is this process performed for each cylinder to verify the specs for all lobes on the cam Or just one cylinder is adequate? Thx.
Perfect understandable explanation, thanks! Now, if I only had the tools.
Hello; I see that many, after set the TDC, put the DTI at zero on the base circle to find the lobe centers; not at max lift.
How is that? Thanks
They never show any of this on the TV shows when they replace the stock cam in an engine. I know it's time consuming, but it should at least be mentioned. Great video.
I watched 3 other videos until i came across this one. All three were shit. Yours was great. Great job, thank you.
I do have one question however. At around 12 minutes we were able to confirm that we have the right cam since the intake lobe was 420 thousandths AFTER multiplying by rocker ratio. Does this mean that the type of cam we have dictates our rocker ratio?
Should you do another cylinder to ensure that all the lobes are ground consistently?
You should do a video on dynamic compression and relation to intake valve closing after bdc
yep I'm working on that it's in part to of cam selection
Excellent video. I don’t have a dial indicator lifter. Can I convert a hydraulic lifter to solid by removing spring and shimming with washers just for measuring purposes?
Yes you can!
That's what I'm doing too. :)
Camshaft Decree: Thou valves shall open on time.
Do u have any videos on how to choose valve springs for ur camshaft?
That's recommended by the manufacturer you bought the cam from...
Should be listed on your cam card... Listed usually in LBS seat pressure.
Hi!

Love your vids, thx quick question.. if I put Vortec heads on a 1988 GM 350 which length pushrods do i use? from the vortec engine that i yanked the heads off, or my original TBI GM block? thanks
if it's a roller cam than use the vortec push rods if not your stock push rods will work
But how did u adjust the timing chain? Don't u have to adjust the chain and lock it in? How does it stay. It's still dot to dot on the gears!
Will chain stretch make the offset worse or better?
Would a belt be better because it's lighter and easier for the engine to turn?
Bravo !!!!! Great video young man, god bless.
I watched a video on here where the man installed the timing set on a dodge engine on the exhaust stroke. Is this correct for dodge engines? Never seen this before. I have all way installed the timing set on all engines on the compression stroke TDC and had no problems.

Why would you pull the heads to remove the cam?
Excellent video young people can learn a lot from you
Hi man, great video, so now how I measure the best timing timing in relation to the camshaft positioning?
Great teacher. love the video.
Glad you enjoyed it!
@@Myvintageiron7512 , I do enjoy your videos. and thanks for the reply.
Dumb question: do you do this procedure for all cylinders, or just one and assume the others are alike? Thanks!
You need only to test #1

Yes it will
Sadly from 2030 on all combustion cars including classics will be banned
from public streets in entire EU and Scandinavia :-( In Germany the
Green Peoples Party gave order to shorten fuel supply from 2025
on by reducing all conventional fuel stations to only one state operated central gas
station per city or county. Now they want to slow down all the gas station fuel
pumps from 20 litre per minute to 2 litre per minute...From 2027 on in
the EU certain car spare parts will be banned too....as exhaust systems,
turbo chargers and even some engine and gearbox oils...California and
New York will do the same from 2027 on.... So no investments should be
done in oil burning cars any longer....They even created a new kind of
crime here, called emissions and smoke crime. :-(((
Do you click on absolutely every TH-cam video and repeat this???? I've seen your exact same statement in the last 20 vids that I watched....
I would have liked to see how to make the adjustment to get rid of the 2 degree error.
would like to see that as well
There are a few way adjustable cam gear , or the most economical way it an off set bushing kit for the cam dowl pin
Is decreeing a cam the same on a Ford since the number one cylinder on the engine is on the left and Chevy is on the right
just use # 1 cylinder
Awesome, very informative man, keep up the good videos!

soo cool, great explanation!
Do you do the same calculations for exhaust centerline?
