Dropping the T-case is way easy. Lots more to get trans out. But I suppose it would be the time if you so choose to do he converter.
I just don't want to wind up missing a digit or limb.  I can sometimes get in a hurry to get results.

Don, I assume you mean a replacement engine build is starting?  Surely you didn't just install headers, to remove heads

Oddly enough, the way the timing of this thing is shaping up, it may turn out exactly that way.

I mean you's guyz threw this T-Case thing on me, so what's a guy to do.

I had planned to tune it with the stock engine now, then get on the cam and heads and intake manifold, but I have the heads already, just a few hours of porting and polishin' away from producin' scads of horse powers, so we is where we is!

Update: I am corresponding with Justin at Black Bear Performance. We are trying to work out my using the Autocal from C-Max tunin' time to download tunes and record engine data. Answer on all that is forthcoming. Meanwhile the cam discussion is awaiting some more input from the builder. I have asked him if, all things considered, do I need to bolt in the converter now or wait?

So, no these heads are not a part of the big inch next engine, however, they will be bolted onto that motor more than likely.

Really, though, I need to get this first combo driving to evaluate it. Who knows it may surprise me and be a good point to stop at...

Speaking of Tate... any update on the Tahoe?


Sent from my iPhone using Tapatalk

The Yukon is still sitting in the driveway with just flat no time to deal with it. probably will be there till after the holidays. Oil analysis came back clean, which only proves they had it in the pits long enough to drain and refill to cover their tracks... we're making due with two cars between the 3 of us for now. I do however have some serious GM SUV envy at this point.

Yea, sorry for your luck, bummer
But
You may be able to recover that jewel just fine

I copy. These big GM's are really hard not to love. I started with them in 2004 with our first burb. Owned a Yukon Denali, an a Caddy Escalade. Both were super fine, just loved them.

This 2500 is more of a bare knuckle bar-room brawler. Not as refined, rougher ride and just "Trucky" everywhere...Just like I like em'

Settled on the camshaft tonight. Emailing with Mr. Joe Vinci, of Vinci Cams, he recommends a pick they call the "Butt-Kicker."
Big HP and torque gains and 1600-6000 power range.

I'll drop that in after accumulating just a few more parts.

Note I just got from Joe Vinci, Vinci Cams:

Don,
1. LS7 lifters & new lifter trays.
2. Use the stock GM MLS head gaskets
3. I would install a new GM factory timing set
4. If you decide to change the oil pump I would use the Melling high volume pump, but make sure you use the correct oil pump tube seal.
5. I would not recommend using the the TBSS intake or throttle body. It will impede the low end performance of your vehicle. You would be better served installing a torque converter.

So, search for TBSS is now over!
Guess I'll go with the factory 78mm Throttle body
Haven't really decided on the oil pump. I mean this engine has had mostly loafing highway miles, steady state where virtually no wear ever takes place.
Torque converter??? Hmmm, Maybe

The new factory ones are supposed to be updated to combat timing chain slap I hear too. let me know what you find out, if I wind up tearing down the front cover for an oil pump I'll be doing that as well.

Really thinking this thing through
I did not waste money on stuff I really did not need
Want?? Why yes, but Need, I don't think so
I picked up a new roller timing chain but did not get either gear
I went with the stock oil pump. A gerotor (Spelling??) style pump hardly wears at all...
If I upgrade to the 408" stroker short block, I'll update that stuff then
Saving on the short end here in hopes of maybe affording a torque converter to get the motor a bit more into the torque band with the slightly taller tire without having to go 4.56

Now I am going to search out a full floater 14 bolt from a 2500-3500 silverado. Should be easy to find. If I need to upgrade gear sets, that is when I'll do it.

Finding a 14bt will be easy, finding one that fits a Sub will not. Most likely you will have to change all the mounts.

I see head gaskets, you doing the heads now? I would do bolts too.

JR, I think in this year range, the silverado 2500/3500 14 bolt is a direct swap into the burb. Dimensions appear the same. Shock mounts, spring pads also look to be exactly the same. Am I mistaken?

Yes, getting ready to port the heads. Afterward I'll bolt them on and slap the cam in as well. Doing it all at once

Yea, the only thing I have found different so far is the rear leaf spring in the burb has a slightly different dimension, about 2" different overall.

Why do I know you ask?

Well, I happen to have a set of brand new Silverado, non HD rear leafs sitting in my garage. Want to install in the burb...may install in the burb...

2001 to 2010 should be the same.

Don't just discount the 9.5 though. They are a stout and have been used for Dmax conversions.

If you have the oil pump out, I would change it.  They have a tendency to gaul the pressure release valve, which causes them to bypass pressure occasionally.

OK, I'm listening. I have wheeled (Hard) on one before. Was stock in my Hummer H2. I remember hammering on it during a long hillclimb at an off road park. If it was going to break, it should have done so then.

2001 to 2010 should be the same.

Don't just discount the 9.5 though. They are a stout and have been used for Dmax conversions.
OK, I'm listening. I have wheeled (Hard) on one before. Was stock in my Hummer H2. I remember hammering on it during a long hillclimb at an off road park. If it was going to break, it should have done so then.

But choice for lockers is poor
Do you have any photos of this h2 you have spoke about?

Finding a 14bt will be easy, finding one that fits a Sub will not. Most likely you will have to change all the mounts.

I see head gaskets, you doing the heads now? I would do bolts too.
JR, I think in this year range, the silverado 2500/3500 14 bolt is a direct swap into the burb. Dimensions appear the same. Shock mounts, spring pads also look to be exactly the same. Am I mistaken?

Yes, getting ready to port the heads. Afterward I'll bolt them on and slap the cam in as well. Doing it all at once
01-05 2500 all the same truck or suv sir.

What was the short list of mods to that?  Looks pretty stockish

Nice acquisition, Don! So, when do you start adding armor plate to the doors, body sides, windows, and windshield? How about a sunroof with foldout mini-gun CROWS system?  :cheesy:
This crows system, have an extra one handy? or a NSN?? ;-))
Merry Christmas there, Army!

Let me look around the warehouse.....LOL! Maybe Santa will be nice to you....if your CARREPs don't put you on the naughty list!

Merry Christmas!

OK, Christmas, done-Check!

So back to the build

I nearly finished the exhaust, just lacking one butt joint clamp to fasten it all back together

The fit appears to be OK, with one spot where the pipe touches a transmission heat shield. I'll bend accordingly

I need more room to place the second muffler in line, using the old MBRP unit I still had off of C-Max. To gain the room I slid the tail pipe hanger aft several inches, then cut 1.75" off the front of the massive 4" tailpipe.

I coated the spotty aluminum shield with some flammable stuff to keep things dicey and safety nazis in tears. then threw on the 3" full band clamps I sourced from Summit replacing that hick crap supplied by the header guys

I had a new 4" lap joint clamp so I employed that sucker keepin' those wonderful carbon foot prints inside the pipage and not leaking all over my rusty and grimy undercarriage!

Mind-you, the tail pipe is not connected to the muffler outlet at this point, but it's close enough to start looking at exit strategies. They sent me this gaudy 5" polished tip thing which is the envy of all the honda kids and can be seen from low orbit, so I'm not sure what I'm going to do here...

Maybe work with it, maybe mount it on the wall, maybe sell it to a jap car kid for $2,500, dunno, but this is the approximate outlet location at the moment.

My Summit supplied porting burrs and a smokin half bushel of cartridge rolls will show tomorrow, so I almost started disassembling the heads...

They look nice. Those are spendy .660" lift dual springs and goodin steel retainers to keep the stuff in the same configuration whilst beatin' the valve seats to an early death!
