Help Degree Cam in Cincinnati - 10/15/19 04:23 PM

I am installing a new cam in my Hemi that will work with
My Holley MPFI system...it currently has a Jesel Belt Drive System, so it will be easier.

I would like to pay someone Local here in Cincinnati that could help me
Degree the cam. It is a New Dwayne Porter cam that he told me to do it right😀😀😀

Would it be better in the long run if you spent the money on the tools to do the job and learned how to do it right yourself? Or am I misunderstanding the situation?

I need someone to educate me, but do it for me...buying tools just to buy tools if I don’t know what I am doing is not on my list.

I will pay for someone’s help to dial it in

A Jesel makes it easy. What I do with a Jesel is install the cam with the line at zero and then just check it. Most of the time it will be correct. If it isn't correct you just loosen up the upper pulley and move it the amount needed. Usually only takes a few minutes. You do need a degree wheel, a pointer and a dial indicator with stand. If you don't have any tools then you'll need to have a local car buddy swing by and help.

Mark I did my first one 40 years ago following a Direct Connection book. Now there are DVD’s showing you how and better pictures in books to help you. If you watch someone do it you will not learn a damn thing. Trust me you can do it and by doing it yourself next time will be a cake walk. PS I’ve had lots of luck advancing them 4 degrees

I understand completely what Lock-Jaw is asking, I am sure he is smart enough and can afford the tools, but would like an experienced person to go through the steps and procedure to make sure it is right. There is alot of piece of mind doing it and seeing it done and understanding it.

Good luck I hope you find a really good guy to help you out.

You would need a piston stop ($10) & a degree wheel (fairly cheap) & a large one is better to work with but are $$$. there might be some utube vids on the procedure. #1 with the piston stop confirm the dampener slit is on TDC on the timing tab (or within 1 degree). EDIT you might search for someone local to come show you, it's a slighly twisted procedure (I had to read the procedure several times) but when you grasp it you'll have it & it is simple: How many degrees after TDC does the cam cyl #1 intake valve lobe reach max lift & I forgot you also need a dial indicator (clamp on or magnetic). MORE EDIT I just checked utube & there are some very good procedures on there

I have some things, but not the degree wheel...the engine is in the car.

What I need is an EXPERT that will help me do it correctly, and I expect to pay that person

If any of you guys are interested in learning how to degree cams in or already do so I highly recommend this tool. It slides into the lifter bore and with a dial indicator installed on it makes this job so more easier, more consistent, and quicker. Christmas is coming, put it on your wish list.

Mark Came over tonight to help me degree my New Dwayne Porter Camshaft, and the Jesel was 5 degrees (retarded) off from where the dot to dot is...The intake centerline was 115*. and that was 5 degrees off, then to add 2* advance, to bring it to 113* at Dwaynes spec. Not quite one tooth retarded, but almost. Boy, did I learn a lot from Mark.


He was a real life saver on this!


Thank you Mark!

I have that tool and I agree, everyone should have that tool when degreeing a cam.

Your cam, is it a Comp cam?

Hi Dave, yes it is a Comp Cam that Dwayne had made for my EFI application.

Re: Help Degree Cam in Cincinnati - 10/27/19 02:22 PM

I recently bought one of the dial indicators that goes into the lifter bore, super great tool. Just as a quick check, when the dots are together that is the overlap period on the camshaft. If you set the engine on true TDC with the dots together, simply look at the lifters and use a small straight edge, if the cam is in at heads up both lifters will be the same height, if it is advanced the intake lifter will be slightly higher, and if the cam is retarded the exhaust lifter will be higher. Not saying you don't need a degree wheel, but it is a quick visual check to see if you are in the ball park. I often use this when installing, gear drives, timing belts etc. Just to make sure everything is close. A couple times this has shown me gears with dots in the wrong place, and if you are reusing a timing chain, sometimes the markings are a little worn, especially on the bottom gears with multiple keyways.

That's good to know and a quick easy check. Thanks

the Jesel belt drive I bought and used in one of my wedge motors was off 2 degree, it was retarded according to there markings whiney
I'm assuming you guys used the lifters for the cam timing, did you use the valve retainers to check the LSA and the intake lobe timing?
If so how did the LSA come out?

Yes - we used the lifter for the timing. We used the center-line method and did it at 0.050" and 0.010" and got exactly the same results. We did not verify LSA.

Re: Help Degree Cam in Cincinnati - 10/28/19 02:01 AM

I've had more than one new cam be off on the LSA whiney rant shruggy
Some of the new solid roller cams with different opening ramps on the one side with a different closing ramp on the other side can get you really confused when checking the LSA and ILC whiney
I normally check the LSA at .200, .100 and at .050 before and after max lift at the retainers with light weight checking valve springs also, that really makes some of the cam grinders think I'm crazy whistling That really helps on finding out what the true rocker arm ratio are also thumbs
They always fix their cams that don't check correctly though up
One of my old drag racer mentors check every lobe at five degree increments on every engine he built, if all the lobes weren't identical he sent those cams back shock work RIP Joe Alread bow angel

I guess we could have gone through the extra work, but I think that the new cam (115 LSA) will be close enough to be great for my Street car. Yes, it is a 605 Indy Aluminum Street Hemi that was 1,090HP on the engine dyno with the old Indy cam, and Dwayne stated that I would most likely lose 50HP on top, however if I lose 100hp, that would not be a very big deal. I had 4" of vacuum at Idle with the 110 LSA, and I am looking for 8-10" at idle. That should be much smoother at Idle at 900 rpm for my Frank Lupo 10" lockup converter driving a 4L80e transmission. I have the Holley Dominator MPFI system, and it really needs a smoother idle. We shall see later this week when I get everything buttoned up.


I will give an update later this week!!!.

Re: Help Degree Cam in Cincinnati - 10/28/19 05:25 AM

Hemi motors are usually very sensitive to the LSA and ILC, you don't want any of the new intake flow going straight out the exhaust on the over lap, do you work shruggy

Re: Help Degree Cam in Cincinnati - 10/30/19 04:28 AM


OK, fired the 605 hemi today, and after retuning, the idle vacuum went from 4" with the old cam, to 13-15" with the new cam!

Will now idle in gear, and is very smooth for such a large engine...so I am happy. Now for the test drive!

Thank you to MarkZ, and all for some good advice.

Sounds like the new cam did what you were looking for. up

You’ll have to report back after the test drive.

260/268 on 115 should be very smooth in a 605 inch engine! Keep the cam card for the original cam in your file and if you decide down the road to shoot for some more top end power you'll know what the limit is. For street driving a smaller cam is usually a much better choice than a big cam. Especially if you are really street driving and not street racing.
