Thanks for this awesome video. At the 17:00 minute mark I noticed you started this and the cam degree wheel was at 180 degrees, I thought you said to have it at TDC (0 degrees). Thank you again, love your vids ♥️
I think I might see, you're trying to find the peak of that lobe or actually the spring retainer (since that's where you set up your dial indicator off of).
Thanks John, I appreciate you taking the time to do this video. This is exactly what I was talking about. Honestly you made it very clear. When I got the notification that you uploaded the video, I literally stop what I was doing to watch the video. I'll do my marauder and share the results. Thank you Sir!!!
Thank you sir for a straight up video without annoying late 2000's rock playing. Some of us are clinging to this insight out of fear of potentially trashing our builds.
Thank you sir! Your knowledge of the 4v modmotor has helped me in many more ways then one! I'm very confident everytime I tear into mine. You have saved me $1,000s
I have been building small block Ford and Modular engines for around 20 + years. I'm glad to see JSR showing how to degree a multi-cam engine. I'm still amazed some guys that have been degreeing cam in block engines just cannot seem to degree these DOHC or even SOHC engines.
I have a '96 Cobra Teksid DOHC block and I am putting on '03 Cobra heads with the Eaton supercharger. I will be using the '96 cams but I am not sure what I should set the Center line for both intake and exhaust. Also the intake sprocket is a floating sprocket (keyless) so I can set it at any degree and also have COMP Cam adjustables for the exhaust. I just don't know a good starting point for a super charged setup on these '96 Cams.
So technically degreeing the cams isn't a mandatory step but just a way to see what type of cams you have. Because there's no way you can change the cam degree unless you get different cams. The TDC for you pistons is what is the mandatory thing to do if you want the engine to not fail catastrophically
I find it interesting he's doing his checking at the valve retainer and not the cam lobe. I would put the pointer immediately behind the wheel. It eliminates a couple different things.
Not that I am aware of. I have done it on several engines and others have too. Later versions of the modular engine Ford went to single caps vice connected ones like the girdles found on the early 4.6 engines.
kudos ... excellent tutorial ... except had to watch it twice, as I was distracted by the fox, with the Bi-Wing and striped tail lights ... oh what was it called ... think I would know .. since I got 5 .. was it SV ... T ..yeah that is it .. FoMoGo had a division called SVT ... it replaced something or other ... Please join Ford Performance on FB ... pet project of mine and all ..
Hello John, I have an 93-94 teksin block that I'm adding C heads with a 1999 Cobra intake. I'm looking to purchase a complete gasket set. Is there a difference between the years? What gasket set do you recommend? Thank you...
I would not get a gasket set, I recommend purchasing the gaskets as needed. The reason I say that is because not all the parts are the same throughout the years. Timing chain, oil filter adapter, and intake manifold gaskets can differ by year. I would get them individually and make sure they fit.
No problem, I was frustrated because I lost a lot of footage on grinding the driver side gears to get the correct centerline. I will probably do another one that focuses on just dialing in the gears.
@@hilliemagwood52 No, you don't have to. Even if you wanted to, you would need to know what the recommended centerline is and I do not believe those numbers are posted. It will be fine without degreeing them.
Hey John, I’ve watched this 100 times and think I’ve got a handle on it lol. But I’ve read that the cobra engineering passenger side secondary tensioner fixes a lot of the misalignment issues on that side, and from what I’ve seen the driver side is a lot of the times nearly spot on degree wise. Do you recommend I absolutely degree my cams? Just a weekend car, 662whp on ethanol as of now. Just looking for that sound while the car is apart, not worried about gaining every oz of power at this point.
Cobra engineering does make a great passenger side secondary. I feel that degree cams is a good idea but I wouldn't say that it is an absolute must. If you have stock cams I wouldn't worry too much about it or the secondary tensioner. But if you start putting aftermarket cams that have a lot of lift or duration then it probably a good idea to degree or at least check piston to valve clearance.
Hi, not sure if I understand the question. The number 6 cylinder is used to degree because it is the companion cylinder to number 1. Meaning when 1 is at TDC so is 6, just one will be starting the power stroke and the other starting the intake stroke. Hope that answers your question.
I have a carbed 4.6 DOHC and I am curious where I should run my timing curve. My timing is dead on, I just can't seem to find any info on where these engines are happy as far as my curve goes. I have it set at idle to 15° and curves up to 26° at WOT. Any advice guys?
That sounds about right to me. I have heard of people running closer to 30 degrees at WOT but it's going to depend on the fuel and compression. You could always dyno it for a baseline then add a degree or two and see if it likes it. If only we all had personal dynos.
@@JohnSmithRacing I have no idea what my compression ratio is. YES, I sure wish everyone had a dyno lol I used to have my compression ratio figured out, but since lost the measurements on everything. I have a stock bottom end from a lincoln mark 8,(Teksid 4.6). -2.8 pistons? Also have a stock set of 2001 lincoln continental C, tumble port heads. 54cc combustion chamber? And I have stock deck height and oem head gaskets. .036 thickness? I know the 96 my bottom end came from had 9:85.1 compression.
@@NoLogoGarage Yeah, your set up is probably mid 9 CR. I believe the B-heads had a bit smaller chambers so going to the larger chamber should have lowered compression some. Either way, I feel you are pretty close on the timing.
Question John, do you know if the same applies to the 4.0 v6? Can't find a vid on one. Want to add 2 degrees on mine after replacing the chains. (No sound on my old phone). Thanks.
How did you pass TDC to get to 2 degree after TDC and then you subtracted your values and divided by 2? I thought you add the values and divide by two moving the needle then to 13 degree not 11? Wouldn’t cam be advanced two degrees otherwise?
Best video on degree a cam. Not even done watching video.

LMAO, The two thumbs down for this video are the guys that watched it 10 times and still cannot degree a multi-cam engine. LOL

No problem, glad to help
Thank you sir for a straight up video without annoying late 2000's rock playing. Some of us are clinging to this insight out of fear of potentially trashing our builds.
I got a question @ 15:29 it was TDC and then after you found the peak of the dial indicator you were about BDC?
This makes me appreciate the money I just spent on adjustable cam gears. Nice work!!!
This is so much more clearly explained than the other 1k videos on UA-cam. Thank you for this
Thank you so much. I’ve been fighting my GT500 cams for 2 days now and you just made it super simple.
Awesome video.

I have been told the factory spec is 110IC/114EC for smog and 108IC/114EC for non-smog cars and that those came from mihovetz
Thank you, made it so much easier to understand this process

Absolutely great upload.
I've got the Aussie Boss 260 5.4 4v and I'll be using this as a reference when doing my cams.
Thanks 👍
John, this is an outstanding video. Are there any adverse effects of cutting the cam girdles? I'm thinking about doing the same thing.
Not that I am aware of. I have done it on several engines and others have too. Later versions of the modular engine Ford went to single caps vice connected ones like the girdles found on the early 4.6 engines.

Do you have to do this when rebuilding an engine and using stock cams?
No, the factory cams are just lined up with the timing marks.
So I'm putting some 98 cobra cams in a 9 thread c head do I need to do this also
@@hilliemagwood52 No, you don't have to. Even if you wanted to, you would need to know what the recommended centerline is and I do not believe those numbers are posted. It will be fine without degreeing them.

No, it is not necessary with the stock cams. The Ford service manual does not even have the procedure in the engine building section.

Yes, the process would be the same.
@@JohnSmithRacing Bless you.
I just received all those parts, the comp cam 4793 won't fit into the trickflow degree wheel is there another crankshaft socket you recommend?
Sorry, I may have typed the wrong part number. The correct Comp Cams part number is 4798.
Can u tune the aviator ecu
How did you pass TDC to get to 2 degree after TDC and then you subtracted your values and divided by 2?
I thought you add the values and divide by two moving the needle then to 13 degree not 11? Wouldn’t cam be advanced two degrees otherwise?
