Bought, wrecked, rebuilding a 2009 LMM

[malibu795]

Well dug this out, air hoses the cobwebs and straw trash.

Pulled the 4088 off opened it up.... I've ran worse before ? turbo spins nicely no play. Some oil and green pad and it will clean up niy

Dropped one of my S300 chargers on for perspective ??‍?
IDK what's the easiest way to keep heat off that PS manifold..




Both Wagler and PMI have replied.. still hashing things out to make sure we're on the same page.

Since Powell no longer is doing regrinds (too much new work to keep up), polishing is going to be a hard option to follow through with.

Hopefully Powell comes through. I know he does cut lobe masters if he does not have them to match stuff as he's talked about it before. Also if there are any things you want "modified" during the process or if he see's things that could be a potential issue when he runs the cam doctor on it, that's the time to make corrections.

Polishing doesn't need to be done on the cam grinder. It can be done in a standard lathe. It's just like polishing journals on a crank with a narrower belt. Takes maybe 10 minutes.

A regrind on the other hand is time consuming. You have to re- index the cam to be fairly centered on the existing lobe. It takes more time to set up then a new grind.

Mid-day mid-week update on cams

Wagler is pretty much set at 2500 for custom 1000 for the cam and 1500 for either clean sheet design or profiling the current cam I have. Says he has a "really close" profile...

Callie's wants 20-25 unit buy in at probably 500-750 each.......

Callie's sent me to Bullet Racing Cams out of Olive Grove MO.... who stopped diesel stuff ~5 years ago.

D&J Precision sent me to Delta Cams out of Tacoma WA. He's more regrinding, but asked for sid by side pic of the Hamilton cam and OEM.

Found Camcraft cams out of Canton NC, talking to their rep, they mainly regrind, and believe the Hamilton profile will fit on the OEM cam. He rough priced me ~500.00 that includes 2 new lobe masters at about 150 each. Pending how well the 3 OEM cams I have sitting here, might send all 3 down.

No News from compcams.

Sent an email to industry injection... Around lunch. Probably won't get a reply till COB or tomorrow.

DPP while they had the cam in their website, they didn't have any on hand, I asked since they recently stopped make the cam, did they sell all their stock or did they scrap the cams and write it off for taxes? Waiting to hear back.

Got a local shop that was Engine Masters winner few times, called them up, they're going to profile the Hamilton cam for $40.00

I haven't asked if I can flat out buy a billet blank yet.

What cores do you have?

 

[malibu795]

What cores do you have?

Either 2 LBZ and 1 LMM or 2 LMM and 1 LBZ, all 3 Rusty

 

[1FastBrick]

Either 2 LBZ and 1 LMM or 2 LMM and 1 LBZ, all 3 Rusty

I believe the term you are looking for is "seasoned"... ?

I still have those other cores from the measuring I did. If you end up needing a core.

If you get a cam Dr. Report on the Cam you want copied, please post it up.

I absolutely am posting the Hamilton 192/200 cam specs.. I maybe a dick, but I'm not an asshole?

Correction
1 LB7 most likely left over my 01 LB7 CCLB that I had and lost the block due to the injectors filling the crank case then GM said F/O
1 LBZ
1 LMM that's keyed

"Seasoned"
Also is this proper use of AN fitting vice adapters?

The rust seams to be all raised, some PB blaster and wire wheel on a drill cleans it up, still has a stain marks, won't catch a finger nail, but I also haven't tried anything dinner either..

IRRC LBZ cam is the "largest" OEM For the 01-16 years, right?

Also comp cams finally replied..

I can help you. Would you have a cam card you can send me so I can match lobes as close as possible? I am looking for the advertised duration #’s as well as the @ .050” and valve lift you already gave me. Also, is there any advance added to the camshaft?
What I will have to do after you can get me the above info, is make a cam card that way you can review it and make sure its exactly what you’re wanting.

That's his response to the "I have an aftermarket camshaft that is not in production and I want to duplicate it, can you do that" type question I have sent out.
In my reply I sent him a copy of the cam card and told him id be getting the cam profiled most likely next weekend.

I'm with Brad on this, I think you're splitting hairs with this Hamilton and a Comp / Callies stage 1

 

[1FastBrick]

That one looks pretty ruff... I can send you the one Josh Donated if you end up needing one for a regrind. If I have time next week, I might be able to key it too for you.

So if you look at my camshaft thread. On the back of the Wagler Stage 1 cam, you will see 270-003. If you look at Callies Duramax grinds it corresponds to there part number. That's how I know it's 1 in the same camshaft. And what I measured correspond to there chart as well despite the other guys telling me I had the lobes backwards on the print out.

Camshaft Interchangable?

I have a wagler stg 1 here but am now ready to install it. Maybe next time Sent from my SM-G990U2 using Tapatalk Here is the specs. https://www.duramaxdiesels.com/forum/threads/can-someone-confirm-cam-lobe-order-for-me.89461/post-1210443 The peak valve lift is affected by rocker arm ratio...

I'd agree, of the redline was 6000 rpm range... Due to the nature of the engine we're splitting hairs by default.
I like low duration high lift cams and tight TCs seams general populous likes high duration low lift cams and loose TCs

 

[PureHybrid]

The Wagler / Callies stage 1 would be smaller in both regards according to the Cam Doctor data posted, with virtually the same LSA

 

[malibu795]

According to Justin at Callie's yesterday, they don't make standard fire cams anymore..
The closest Callie's crank is
270-002/270-008....185/187° at .050" with 471/475" with a 110lsa but those are Alter fire

Probably because they sell more of the ALT Fire cams. plus they make more money too.

If any of those stage 1 Std fire pop up at discounted price I would buy a couple more...

 

[malibu795]

Comp replied
24924 duramax lobe which is 194/0.347" with 1.36 is .471"
23233 duramax lobe which is 202/0.304" with 1.68 .510"
And can advanced and adjust LSA.
This closest that's been told me..

 

[PureHybrid]

What do they charge for a custom grind? They have a couple grinds like the Tripower and the Stage 2 LST that are very close already

 

[malibu795]

Yes these are the publicly advertised cams
132-302-13 194/208° at 475/475
And
132-501-12 197/202° at 450/450

Hamilton is 192/200° with 480/509
And the suggested cam is
194/202° at 471/510
He's been responding at the end of the day, I'm still going to do my due diligence to plot the stuff out to verify clearances

 

[PureHybrid]

I would imagine you'd be fine if he gives you their TDC lift, which should be less than the Hamilton unless Comps ramps are slow af. What springs were you running on the Hamilton cam?

Ran stock springs as I don't think I ever spun faster than 3000rpm, 1800-2700 is my normal rpms 99% of the time...
definitely putting set of 120-130# springs in, which will probably bleed to rocker bridges and pushrod upgrades as well.

Forgot to ask if I can get lift at 5° intervals starting at 15° BTDC to 15° ATDC for each lob one a 110° LSA
