Bought the truck in 2006 with 6,000 miles. 4.8L/4L60/2wd It has been a fantastic truck. Probably the most fun truck I've owned. Over the years I've been slowly gathering parts, reading posts, and rebuilding nearly every system on the truck. Its time for my performance truck thread!
Last spring I was lucky enough to purchase one of the performancetrucks.net moderator's supercharger setup. Right place, right time. I've wanted a blower since I was 7 years old. Finally got it!
My boss thought these photos were hilarious and told me to post them.
This is me eating dinner with my blower.
This is the blower tucked into bed.
Before I stumbled across the blower deal, I had already built my own dual 3" exhaust system. Long tubes, x-pipe, Borla XR-1s, w/ bumper exit truck tips. I posted a thread on here years back about the exhaust. Its been good. Just about as loud as I could get away with. I caught some crap for putting that much exhaust on a stock 4.8......not so silly now.
I've rebuilt the entire front suspension and steering. No photos, but who cares. I've rebuilt the entire rear axle/suspension. New Yukon posi, 4.10 Richmond gears, Yukon axles, bearings, seals, blah blah blah.
I stopped by Jake's Performance Transmissions and picked up a 4l80. I put a Yank 3000 stall converter between it and the gutless 4.8.
I snagged a carbon fiber driveshaft from a member on here 8 years ago! Lol, I've been squirling parts for a long *** time! Funny thing about the driveshaft. I don't need carbon fiber. At the time, I was searching for a yoke. I mentioned to one of my buddies, "Hey, theres a carbon fiber driveshaft on the boards. Think I should get it?" His reply was "Remember in Gran Turismo when purchasing a carbon driveshaft was the last possible pimping you could do to a car......" So I bought it! Peer pressure!
Stop what you are doing, and go buy one of these corded underhood lights right now! I've seen many of you with these lights and its a serious game changer.
You need to clearance the power steering bracket for the blower tub. I didn't get a fancy photo when I was finished, but you get the idea.
Cleaning the decks was a real pain in the ***. That took a lot longer than I expected.
Got a cam speced from another mod on here.
Tossed on some new gaskets and TSP ported 243 heads. These have the light weight valves.
TVS2300 is a big blower for a 4.8! The spreadsheet Atomic wrote says I will be seeing between 10-15lbs with a stock crank/3.4" on the blower.
I have pulleys that will lift heads, ruin pistons, and fold rods in half. I plan on building up a forged short block so I can actually use the blower. Right now its just yawning.
I got my first few tastes of boost over the past couple days. I really like it! The truck seems to like it. There is still plenty of work to be done. I have a bunch of wiring that was setup as "proof of concept." Now that things are working as intended, I can get wiring and gauges sorted out. I snagged one of those full length consoles. I plan to get that setup with a few more gauges. Should look like an airplane cockpit after too long!
Big shout out to Atomic for the motor mounts and tuning.
Big ups to Vortec350ss for the cam.
BlackGMC, a very heart-felt whoop whoop on that blower setup. This truck has been transformed into a GD animal.
I'm right at 1 year and 25k miles with my TVS1900 on my bone stock 4.8. Its got a 2.6 pulley and sees 16psi in warm weather and up to 18 when its cold out. Atomic tuned it and I haven't had a single issue with it so far.

Nice truck man!
Word. Thats encouraging.
I haven't matted it yet, but rolling into the throttle is so much freaking fun! This is exactly what I was going for.
