5.3 DoD Delete Stock Replacement Cam -- What's the Verdict

[TNBob]

The camshaft in our engines is "parked" at ZERO.. The VVT can only retard the cam timing.
It generally does this at higher RPM to make our 'little' cams seem "larger" at more rpm.
The factory cams are really small & that's OK with VVT because they can act like a big boy cam
when commanded to do so.

Yes, by full advance, I meant zero, but zero is precise! Like the description of how it works.

did you ever figure out what cam you wanted? I am going through the same deal right now. Mine is a 2017 Tahoe. Still trying to find out what engine I have. Hahaha. I was just going to put exactly what came out and keep it stock. Run good motor oil and hope for the best. I didn’t know there was a stock GM cam that was a dod delete?

Hello,
I appreciate its a few months later.

I have the same engine (lmg) and used a L96 cam, removed DOD but kept vvt.

So L96 cam is closest to stock LMG? Notice any difference?

 

[Ivanhoe]

@mikez71 No noticeable difference, runs fine. I saw it on several sites as part of a dod delete package.

I used this one when I did the delete. Truck runs great and I do not notice the loss in H.P...

• 12689035 (190/191, 0.466/0.457, 114). This one is the default “stock replacement” cam sold with many DoD kits, but it is a bit anemic. It is the same cam used in the LMF 5.3 engine (VVT but no DoD, found in Express/Savana vans), which is down about 15 hp and 15 ft-lb from the LMG.

Gwatney and Cam Motion have Gen IV VVT camshafts.

You don't need a spring upgrade with .500 lift.

I love my Cam Motion cam, but I just checked and they don't yet make a VVT camshaft. Texas Speed and BTR I believe both *do*, however.
