It's content like this that makes it all worthwhile. Surprising how clear the coat hanger can indicate against the wheel.

[@Alexsvt03]

Very extensive but thorough! Nice video

[@DB4DGAMING]

Awesome content! I appreciate you a lot man! Keep up the good work. Look forward to your next video.

Just found your channel love this video very informative

[@jamiesvt]

Love your videos great job! keep it up !

[@TimsElite]

Hope you see this. But I just got one of my heads back on. I set the timing back up, lining the marks up correctly. But as I turned the engine to install the cam followers, the engine gets "jammed". I have the engine on the ground and the trans is still mounted. I'm hoping that I just dropped something in the bell housing. Could it be something else?

[@cobraengineering]

If it's jamming without the followers it has to be something else. If it jams when the follower is in that means a valve is in and you should double check the timing marks.

Great information. Besides adjusting the cams to get both sides close to even, say I wanted to advance the intake and retard the exhaust would there be a performance gain? I was thinking intake installed on 108 and exhaust at 120.

[@cobraengineering]

I’m not really sure about that. I wouldn’t consider myself a expert on cam placement. But that is a big move.

[@007-b8i]

@@cobraengineering yes a big move for sure, well thank you again for your input.

[@ricardoduran1740]

Do you have to degree the cams as well on stock 04 cobra cams or only if you using 96-98 cobra cams???

[@cobraengineering]

I like to do it no matter the cams. Because timing can be different from one side to the other.

[@ricardoduran1740]

Ok and is the same process you did on your video?

[@cobraengineering]

@@ricardoduran1740 yes.

[@jordanwendell6279]

So you do all your degreeing first, and then make adjustments where needed after so you’re not repeatedly taking gears off to grind them down either way if necessary?

[@cobraengineering]

This video was more about the process. But because I didn’t have a cam card with a target centerline I was more concerned with the banks being the same than what the number was. If I had a target centerline I would have adjusted each one as I measured. I did get them to within 1/2*.

@@cobraengineering thanks for clarifying! Decided I’m gonna try and tackle degreeing my cams and having everything right, so just looking for the best practices lol. Thanks again.
