    New PB

    Slowly getting the transmission tune dialed in after the 6 speed conversion. It's still not totally happy or doing quite what I want it to, but it's getting closer. Took 3 tenths off my best from last year at the same MPH just by getting the power down better. Still could launch a bit harder...

    Melling M561

    I'm rebuilding the LB7 in my utility bed, and need to replace the oil pump. It looks like about 6 months ago Melling released the M561 as an upgrade to the M316. From what I can see it switches from the stock spur gear design to a gerotor. Has anyone tried one of these? Can't find much...

    CP3 Gear Install / Torque Spec?

    I am replacing the CP3 on my Suburban with an S&S SuperSport. It didn't come with the CP3 gear or adapter plate, so I pulled them off my stock CP3. Man, that gear was stuck on the stock pump! Had to use a puller and heat before it finally let go. Given how seriously it was installed on the...

    Fleece Freedom Series Heads?

    Has anyone run Fleece's Freedom Series LB7 heads? Curious about everyone's thoughts on them. Backstory: I warped the heads on my Suburban. Will be about $500 in machine work to clean them up. Add another $1100 for screw-in cups. Fleece has these heads on sale for just under $2000, and I'm...

    GMT800 climate control automatic (CJ2) to manual (CJ3) conversion

    People have been complaining about the lack of tech here lately, so I thought I would completely misunderstand the assignment and share a project I am wrapping up for a friend. Is it tech? Technically yes. Is it stupid? Also yes. Behold: Converting Automatic Climate Control to Manual: The Hard...

    Changing turbo setup

    I've had my motor built for about 5 years now, and I have an old Trent Nell / EPR turbo kit. It's a S371 with a clipped 74mm turbine. It has made 700+ HP but I mostly run it on a 660 HP tune to try and extend the life of the turbo, with limited success. I've been toying with the idea of...

    Steering Box for Quadrasteer Suburban

    I have a 2003 Suburban 2500 Quadrasteer (w/a LB7) and the steering box input shaft seal started leaking. The box still feels tight, just leaky. I believe the part number is 19330624, and it appears that box is unique to the Suburban 2500 platform (including Yukon XL 2500, H2, and Avalance)...

    Another '03 LB7

    Picked up a 2003 GMC Sierra 2500HD CCLB LB7 4x4 with a utility bed on it. I have always liked this style of utility bed where it matches the body lines instead of just being a big square box. It needs injectors BADLY, so I towed it back to the farm: The body is a bit rough, and it needs some...

    S&B 10-1023 LB7 calibration

    As with all my scripts, they are in metric, so set EFILive to metric first! I just installed a S&B 10-1023 "62 gallon" fuel tank. By my measurements, it is 56.2 gallons total, with about 54.7 gallons usable through the included fuel basket. Might be able to sneak a bit more out through the...

    Software upgrade growing pains & wins

    Overall, looks to be a good start on the migration, and I do think this will be a nice long-term improvement. I'm sure Jimmy & The Fish are aware of most of these, but I thought I'd put up a list of what I've noticed so far. Unicode / UTF-8 decode issues on old posts. Specifically, apostrophes...

    Attachment Quota

    I'm trying to attach a couple PDFs of schematics to help a member diagnose an issue (thread, post), but I seem to be 8.3MB over my quota somehow. I guess the quota was reduced at some point? The attachments are pretty small (<300 KB total), and would be useful information to keep around. I hate...

    LB7 injector HP line socket info

    How is everyone doing LB7 injector lines without a crows foot? Does everyone just guess on the torque, or use the old pull-on-a-wrench-with-a-spring-scale trick? I always use a crows foot to tighten them up, works really nice. Having the right tool can make all the difference, though. Looks...

    Raced the Pontiac Grand Prix

    Firebird had their midnight drags last night, and I wanted to shake it up a bit, so instead of my truck, I brought my 1998 Pontiac Grand Prix GTP daily driver. The car has a L32 in place of the stock L67 (because I seized the stock one) with the Gen V supercharger. It's got 60# injectors, a ZZP...

    Killed a CR-V at the strip

    I didn't get a chance to get to the drag strip yet this year, so made it a point to go to the last blast at Firebird today. Brought my 1998 Pontiac Grand Prix GTP daily beater to test if my new intake/downpipe helped (it did, gained 9 HP :roflmao:). My friend brought his bone stock 2017 Honda...

    HTTPS Side Effects

    First of all, I didn't even notice, but at some point you guys switched to HTTPS. So props to the admins for pulling that off 99% trouble free. That is often not as easy as it sounds. :thumb: I did notice one minor bug now that the site is HTTPS. In the iTrader plugin, when you are leaving...

    Winivan the Race Minivan

    I mentioned my "race van" in another thread, and people expressed some interest, so I thought I would write up a quick build log. But first, here is the completed project: If you just want to scroll through the photos and laugh, go right ahead, I don't mind. If you're curious, feel free to read...

    Retained Accessory Power (RAP)

    I wanted to get a high-amp Retained Accessory Power (RAP) source in the least ghetto method possible. I searched around online, and couldn't find a good guide, but I eventually figured out this method. This replicates how GM supplies RAP to the sunroof. If you have a sunroof already, you will...

    CV Boot Squeak

    My Suburban recently developed a squeak in the front end that matches vehicle speed. Jacked it up, and it was coming from the passenger CV boot. I put some silicon spray on the boot, but that made it much worse. Cleaned that off and sprayed it with WD-40, and it was silent! For 2 days. The boot...

    LB7 Quadrasteer Suburban

    Well, I'm officially a member of the Duramax Suburban club! My brother and I put this together last Christmas, and I ended up buying it from him over Thanksgiving. It is a 2003 Chevrolet Suburban K2500 LT Quadrasteer, fairly loaded. Heated seats, power adjust pedals, etc. It was an Oregon...

    2001 4.8L dual-tank OS

    My friend and I swapped a 2001 4.8L into his old 1984 Ford pickup, which has dual tanks. I would like to get the GM ECU controlling them, but I can't seem to find a 2001 OS that supports dual tanks. His current OS is 12208322, so if someone has that with dual tanks, I can segment swap, but I...
