    What would you buy if you had to replace your GMT800/900 SUV and couldn't buy a GM product?...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    This is my current situation. I have dual batteries run in parallel, and both are dead. I can jump start it, drive it for 20 mins, and it'll start fine for a few days. Usually after 4 days of sitting, it's back to being dead as a door nail. I even have a mechman 250amp alt, and good copper...

    What Transmission do i have

    I don't think Denali's ever had a 5.3 option in 08 or at any other time?

    Blackbear Performance Review

    It's odd that this article says the L96 has cathedral port heads, but those came with the 823 rec port heads.

    Need some advice on which direction to go

    I wanted to start to figure it out, but now it's stone cold dead. I have dual batteries that are maybe 4 years old, and a mechman alternator. I drove it Friday and it was fine, but yesterday it's dead enough that the interior lights don't come on.

    Need some advice on which direction to go

    Mine is doing the exact same thing, it happens when I put it in drive or reverse (I either park in my garage or out on the side street). This is on my 09 Tahoe with a modified L9H.

    Seeking Experience/Opinion on Half-Worn Michelin Defender LTXs M/S in Winter Conditions (vs. A Prius w/ New All-Seasons) -- UPDATED

    6/32 will be fine with those tires. I have the same ones and I have about the same wear on mine. I just drove the Eisenhower (high up in the Rockies) over Thanksgiving and had zero issues dealing with the snow up there. I do have 4x4, and only used it in the deeper snow in Silver Thorne...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    What did I miss here? I'm assuming a engine transplant, but somehow I missed what you've had done.

    6L80 video for 1000+ hp

    I noticed that too, and they seem to use both channels now. But they stagger the videos one day apart. I like them and learn more each time I watch their videos. I'm also a fan of Nick Transmissions videos too, and find them very educational.

    Acoustic laminated glass

    As far as I know, there are NO Tahoe's that have the acoustic laminated glass, not even the high country trim. But I think all Denali trim have it, even the AT4 trim has them.

    Thoughts on 25 Yukon Denali giant screen?

    What cam did you go with, why, and do you like it?

    I was just checking the site out, and it looks like Texas Speed doesn't offer VVT cams anymore. I bought mine about 3 years ago, maybe the demand wasn't high enough for them to keep making them.

    What cam did you go with, why, and do you like it?

    I went with TSP VVT-1 cam and I absolutely love it. There is torque all through the powerband, and after 4500 RPM it feels like the front end gets light. All I need are flaps and I could probably fly! Also, driving in the Rockies with this cam, almost makes my 6.2 feel like a diesel pulling.

    Thoughts on 25 Yukon Denali giant screen?

    I agree, the screen looks horrible. What gets me most about the refresh is the terrible quality of the leather on the seats, they look like more vinyl was used then actual leather.

    OK, Bought a 07 with a couple problems today.

    I have tried to find where I got the info on the 5364 heads being problematic, but I couldn't find it anywhere. Therefore, I guess it looks like I'm wrong.

    OK, Bought a 07 with a couple problems today.

    Hmmm.. When I was doing my research before building my 6.2, I remember it being the 5364 heads that had issues. When I get off work later, I will try and find the info I found back then. I definitely don't want to spread false information.

    Major upgrades GMT800, 06ish XL 2500

    https://www.zerogravityperformance.com/product/gen-1-2-gm-engine-6l80e-6l90e-6-speed-conversion-kit/?origin=serp_auto Seems the 6L80/6L90 swaps are becoming easier.

    You may want to Google info about those 5364 heads. I believe they have some issues, so if your current engine has 821/823 heads, use those instead

    OK, Bought a 07 with a couple problems today.

    I just installed the same oil pump you've listed and my oil pressure at cold idle is 60psi, and hot idle is 35-40psi. Long story short, my oil pump was replaced when I built my motor a few years ago, and it was an AC Delco replacement. It 100% failed on me with less than 30k on it last month...

    I put the new pump on, and got everything cleaned up to put this all back together this week. I've been sifting through the oil, and so far I've only come across 2 small pieces of metal, but it looks like it came from the oil pump. Here's some random pics

    PPV, does someone have a list of all differences?

    There are kits that remove the optispark and change to coil near plug ignition. I'd love to have another 96 Impala, I miss mine.

    Yeah, I'm going to pull the pan for sure. I'm almost certain it's the oil pump, because the last test I did was put a new empty oil filter on and started the engine. The new oil filter didn't get a drop of oil in it, and that's why I believe the pump is at fault. The pan will be pulled off...

    I think I got a bad oil pump. When I was building this engine, I ordered things from rockauto, but at the time I didn't pay attention to their 'gold' line and thought I bought genuine GM parts. I'm thinking I bought an inferior pump.

    I got the front of the engine pulled apart, but not the oil pan yet. I can't remove the oil pump yet because of the pick up tube bolt, but I wanted to make sure I'm having pump issues so I pulled the pump cover. With my pick, I felt the relief valve open and there are scoring marks on the gear...
