GEN IV W/cylinder shut down I read before but cannot remember what to do to eliminate the newer GEN IV cylinder shut down setup on these newer motors, just use regular lifters or what? Just scored a 2008 5.3 for a friends and realized it had the pressurized valley cover for the lifters to activate ect. What neds to be dont to put a cam in? I though just lifter.

Most performance cams are ground on a 3-bolt core. Just need to swap cam gears to the 3-bolt, non-DOD style and replace the DOD lifters. If you're going for "looks" (and that DOD cover is one fugly mother!), swap the DOD valley cover for a non-DOD cover and either use the factory o-rings or drill, tap, and plug the 8 DOD risers in the valley. Some say the oil pump will put out too much pressure, not too sure about that...

Down the page is a list and part numbers that I'm going by. I have a 2009 5.3 that I'm doing the dod delete and putting a carb/cam in. The cam I bought is a single bolt cam.

I 'think' you're OK with the single bolt cam, but either way, you will prolly need to buy an LS-2 front cover. In addition to the above, once the DOD cam sprocket is deleted and swapped for a standard 4x gear (single bot or three bolt), the cam sensor will be too far away from the gear with the DOD cover to give a good signal.

I knew there was a single bolt vvt delete kit somewhere. This may or may not work. But sounds promising.

Jsanford, I think we just confused the issue,
If your engine has vvt, you will need to replace the front cover,
If your engine does not have vvt, you simply need a single bolt 4x top cam gear , or change cam AND top gear to 3bolt for the cam drive. Both single and 3bolt top gears are available for 4x
Edit frickin iPhone auto correct lol

Thanks fellas, that should be all i need to know, it will be getting a cam and LS2 timing gear, i figured plug the risers and change lifters and trays and i would be set, so if i change the pan to a F car like i plan, a regular oil pump will be fine, that is good, i accidentally picked this motor up not paying attention to the valley cover.

So is all the changes worth it with the later model 5.3 motor? I'm sure starting to question mine. I got a smokin deal on my 20K mile 2009 5.3 ($600.00). But with all the extras (LS7 lifters, cam, pushrods, valley tray, vvt delete.) I feel like I could have just bought a 6.0 to begin with. I'm over $1000 now with the parts I bought so far. And I still need pushrods, and the VVt delete.

Yea, with knowing we are swapping cams and going carbed, it is still worth it for the fact we got it and a 2002 5.3 for 1000$, the 08 model has 243s, not that they are different from 799s.
For people like myself it is still worth it since i do this so often that i have extra lifters, trays and other valve train parts readily available. If you are not like me, then you would want to hold out for the non DOD/VVT model.

So far, I have a comp 220/220 581 581 112lsa cam with a vic jr intake/750 edelbrock. I'm hoping for atleast 400hp on the motor. It should be fine for what I need it for. The motor has the 799 heads.
So far I've picked up some...
LS7 lifters (under 5k miles) for $20.00
LS2 valley tray $50.00
Comp Dual Springs with locks (less than 2k miles).....$125.00
Value shopping..

Those are over 300 all motor stock, so i assume a cam, induction and headers will have it about 425ish usually, perhaps more depending on other mods, ect.
You are going to love that cam, the one i have is roughly 226/230 on a 114, so the power band is just up a bit too high, yours will be very happy with that im sure.
