Best explanation and visual of Cam Voodoo on the net. Not Voodoo in a bad way, thanks for a peek behind the curtain and taking the time to enlighten us.
I was wondering if this was feasible. Of course this grind would require compensation in the form of adjustable rocker arms, or larger shims. Would be good to explain that too.
Literally just got inside from installing a reground camshaft. I am more excited to see how this one turns out then any of my previous builds honestly. Only thing I was told is the gm billets are softer then after market so can't run a bunch of spring pressure but bee hives gives me exactly what I need for this street motor.
I did this with a Briggs and Stratton 5 hp cam on my “box stock” race cart. Made a stand out of bearings and used a belt sander to remove material. Welded the tip on the push rod and made the appropriate addition. Yes, I was much faster, especially after the twist on the cam.
Keep these videos coming Jon! Cam grinding has been a mysterious and almost black magic topic for most gearheads, including me! I'll be messaging you soon about the last video, regarding the surface process you posted about a week ago.
Thank you for your interest sir.. feel free to share these videos on any social media platform you have and have them "Subscribe" to my channel as Im just getting started on getting it dialed in with actual video editing and new Hi Def 4D video footage !!! Gonna be AWESOME !!
@@DELTACAM8005625500 i would love more info on this. This is an art i would really like to learn. Would be fun to tinker with some small engine cams . could you recommend any literature on cam grinding?
This takes me back to the machine shop days. I would set the machine up to grind a cam and when the first one was done, the boss would take me off and put Davie on and he would crash the machine. Never failed, course Davie was still in the Navy between his ears. What a fork up for sure. VF
What ppl don’t get I think if you tell um that you checked a valve clearance when the cam faces up it might help um out , good video 🏴👍🏼 I wish we had more access to this knowledge in England it’s hard to find places to do it , and the ones that do it’s cheaper to buy new high lift cams from America 🇬🇧👍🏼
I used to watch Mike Brewer and Edd China and it seems the UK has many more shops for all sorts of repair and modifications than the US. Just my impression.
I am intigued by this process, not so much for extra lift but closing up lsa if possible. Can a 112 be made 109 [starting with 0.460" lift]? The business of shifting lobe centers would change some behaviors obviously.
Informative video.....I wondered about this Exact Same thing for a Long time when I first discovered 3/4 Race & Full Race "Re-ground" Camshafts advertised in Sears Roebuck Catalog back around '62 when I was 12....Just couldn't figure, Without welding metal on, how do they make something Bigger (.510" is better'n .450" lift) by Grinding metal off ?? ........7 yrs Later, holding my new "Reground" cam, I quickly saw how it was done !! .....Thx for showing.....

I'm guessing that the extra lift is achieved by using a longer valve stem after this adjustment is done? and by changing the diameter of the base circle, you increase the length of the opening and closing ramps?
Have you ever ground a diesel engine cam. I am wanting more duration to get more air... I dont know anyone personally that has tried this for Diesel application
Can you grind a cam for a 3406 e caterpillar so that on the injector lobe so that it eliminates the secondary injection pulses mechanically so basically a complete round I.B.C on the injector profile and if so is this something that you would be interested in doing
Re-weld and grind service available for cars with "shim" heads? In this case is for Nissan GA16DE cams. This motor no have aftermarket support. Really interested. Thanks!
that is a great question.... if its a mild - midrange grind no longer pushrods will be required as the Hyd lifter has up to .100" internal travel. so the lifter will make the adjustment. For heavy rv or race grinds then yes usually a + .060 pushrod will be needed.
Thanks for the quick reply! What camshaft would you recommend for a 360 in a 1975 1 ton van all stock except for a little bit of pocket porting, headers and a 3 angle valve job? I'm not too concerned with economy (not achievable in a mobile brick) but would like more pulling power from idle to cruise speed (2,900 rpm @ 60 mph). BTW, it has a 3 speed auto and 4.10:1 rear ratio.
I have heard that cam profile changes have an effect on smog and that might be something to consider. It is my understanding that in 1975, all vans had to comply with smog laws and were subject to testing.
Hey I’ve got some regrinds for a dohc and I’ve added a .080 lash caps and .110 shims under the lifter adjuster. Is that too much? Did the cam place grind too much away ? With that much shims and lash caps I’ve got the preload where I’d like it

That's the part that is missing!
I wish I would have worked with you guys 30 years ago.
But I appreciated the cams I have gotten from you over the years. Thanks.

These guys make some really good Circle track cams

I got one lobe with slight indentation praise be to YAH I’m feeling to modify that baby! Yea Bo!
If you resurface valve lifters, I would like to see how it is done and the type of equipment needed to make the crown.

Awesome video! Thanks for showing how it's done. Do you heat treat or harden after grinding?
Heat treating is over 200thou deep, we'd never grind that far.... feel free to drop the vid on your socials
Very interesting..learn alot

The length of the ramps/duration is not necessarily changed at all when the camshaft is ground to increase lift.
This is awesome what is the cost to grind Honda b series Cam's? Have you ever heard of people grinding them themselves?
Well said .
Dont grind the top lobe just hover the camshaft back and forth in the lower lobe so it will not affect the height
Have you ever ground a diesel engine cam. I am wanting more duration to get more air... I dont know anyone personally that has tried this for Diesel application
Damn more vtec
Can you grind a cam for a 3406 e caterpillar so that on the injector lobe so that it eliminates the secondary injection pulses mechanically so basically a complete round I.B.C on the injector profile and if so is this something that you would be interested in doing
That's a good question, did you ever find someone who could do that?
@Mark_Tschetter nope but I'd sure like to find someone that would like to try I have extra cams sitting around
Ok, I thought so but were can i find adjustable rockers.
Have you guys ever worked on Suzuki H27A cams? I am vert much interested in getting a quote
merhaba
çok güzel açıklama..kralsınız..teşekkürler.
Still for the life of me can't understand how this works thanks tho
Nice! R u still grinding? Or did u retire?
great vid.
Fine tutorial!
I just purchased a new High Definition Sony Handycam for 4k videos Ill post one later today top compare quality vs cell phone videos
so grinding a factory core to comp 270H specs, can you change lobe sep to 110, or are you stuck with factory centers?
Yea, but a close up of the grind tells us what we already know. The meat and potatoes is left out
Jon how do you work out what you need to remove off the camshaft is there a special formula to work out lift etc ?
Re-weld and grind service available for cars with "shim" heads? In this case is for Nissan GA16DE cams. This motor no have aftermarket support. Really interested. Thanks!
yes we can do them $150 each, verify tuning prior to getting cams :)
JonneyBlazeRacing Thanks! Very good news!
@@DELTACAM8005625500 for the toyota 5efe as well?
You still do them
Will this affect the hardness of the cam??
Good question..... the factory hardness is over .200 deep, will not grind anywhere near that
beautiful vid
Where are you located?? Could I send an old honda cam for regrind?
Address is @ Deltacam.com
How are the lobes indexed from one another ?
Is it possible to get the sequence wrong ?
I have a Nissan Ka24e 2.4l turbo its sohc. I would like a custom camshafts for it. How much do you charge.
Requires adjustable rockers
Great video, how would a person know what the right degree for a standard camshaft to be cut a into performance CAMSHAFT..??
If I purchase a custom grind for a 360 Dodge with non-adjustable valvetrain do I need to buy longer pushrods?
that is a great question.... if its a mild - midrange grind no longer pushrods will be required as the Hyd lifter has up to .100" internal travel. so the lifter will make the adjustment. For heavy rv or race grinds then yes usually a + .060 pushrod will be needed.

Tony Shade 260 is a great option for your build.... cam & lifter kit $120 regrind or $180 new

Hey I’ve got some regrinds for a dohc and I’ve added a .080 lash caps and .110 shims under the lifter adjuster. Is that too much? Did the cam place grind too much away ? With that much shims and lash caps I’ve got the preload where I’d like it
They ground off of the base circle which is required and it’s also the point where you set your lash.
Can you regrind azera 3.8 cams??
send pics of the cams to sales@Deltacam.com
boosted views :)
