2012 yukon denali awd dod delete, cam, converter
would it be easier to do the DOD delete with engine still in truck and then drop transmission/transfer case to install converter, or just pull the engine out to do both?

ok, that is which way i was leaning...pull the whole thing, work it on a stand. Been a while since i rebuilt an engine, wasnt really looking forward to leaning over fenders for 2-3 days.
218/228 .600/.600 113lsa VVT cam, circle D 278mm 3k
oil pressure relief....? got any good links to removing *** nevermind, looks like it's just as it sounds lol, a threaded relief valve, take it out put in a plug

Not to sure, looks like the afm is definitely reliant on it, vvt should be fine as long as oil pressure doesn't go crazy 100+ psi. The engine was just replaced by gm under warranty a few months ago, at idle by the dash gauge it only shows 25-30psi.

I just done a build similar on my 2010 escalade. Forged pistons/rods, DOD delete, (kept the vvt), mild ported heads, custom grind cam, speed engineering 1-7/8'' headers/no cats to stock muffler. I wanted to keep the stock convertor.
It sounds VERY good!! I dropped it off for tuning this afternoon.

nice man, any build pics? I bought the same headers/ypipe how did they fit (awd?) and plan on using stock muffler from there back too.
I wanted to get the heads CNC'd but that got the axe as the costs started adding up. I am throwing it back together with head studs, ls9 gaskets, hardened pushrods, pac 1219x springs, and ls3 valves ... at some point it may get a little boost just not sure when or how.
I was pretty much set on regearing to 4.11s to get it moving a little easier although the 3.42/6l80 combo works good for me. when I realized the stock one flashes at 1600rpm i figured swapping it out would help just as well. circle d talked me out of a smaller single/multi disk said the larger one would have better part throttle response

For the money the headers CAN'T be beat! There a little tight on the driver side but are fine. Make sure your motor mounts are good. I had 1 bad one so, I just replaced both. I had to do some fab work to make the factory connection work (no big deal). Mine is AWD as well. I built mine with boost in mind down the road also.

Ya'll not worried about tuning with boost and VVT? I want to boost mine too but I'll wait until I find a deal on a Procharger or LSA. So in my mind I'll wait until I figure out what type of boost I'm going with before I cam it.
So my question is do you thing a VVT cam can go with either types of boost. If so I would cam it now for alittle bit of bump in power.
