    Lowering a k3500 4wd

    What about a gmt800 knuckle swap? If you can get lowering knuckles for a gmt800 I'd go that route. Also gets you far superior brakes. Lawrence LT Tolman on YouTube has a good video going through the swap on his suburban. He mentions using 2500ld knuckles because you can keep the stock tie rods...

    Ls swapping a 95 k1500

    I'd keep the 01 drivetrain all together. At worst you'll have to get a controller for the t case if it's electronic.

    Sound deadener

    I spayed down bed liner then used dynamat dynaliner on my floor and back wall and it made quite a noticeable difference in noise and heat especially around the foot wells.

    Really stupid question about dual exhaust pipe sizes

    I have found that the smaller the pipe and/or less crossover the more crackles and more drone. 1 of my trucks has shortys 3" collectors that has been y-piped into a single 4" into a modified flowmaster 40 that's single 4 in dual 4 out(used to be 3in dual 2.5out which was a little too...

    Header bolts

    Yes those will work great, I believe the flange on the head is serrated so it won't back out, if not and you're worried lock washer it assuming you have enough thread engagement to do so. Personally I dont use lock washers as I haven't had an issue with them backing out. Just a word of advice...

    Engine knock (newbie)

    Can't tell for sure by the video but it does sound a lot like a cracked flywheel in the first video and either a seized bearing or the fan just scraping the shroud in the 2nd video, as mentioned by "Texas tough" take off the serp belt to find out if that eliminates any of the noise. If it...

    Just wanna tow a 2000lb. Trailer up a hill..

    Never had knock issues till I started boosting it. Ran 87 octane but temps here range between -22 and 100*F I agree but it's free to do Not if you take your time and use a block off plate to limit the welding, and set it in some, I did checked it after with a straight edge didn't warp. If...

    95 14bff one legger fix?

    I bought the Eaton truetrac for the corporate 14bolts (10.5) a year ago for about $800cad to my door from summit. Honestly by the time you buy the 11.5, buy new gears, swap and mix and match parts and then having a crappy g80 at the end of the day, the truetrac is the best option and cheaper in...

    1999 K2500 Fuel Tank Swap

    Not sure if the Yukon 30gal tank will fit but you'll still need to figure out the filler neck. Here's a pic with dimensions to check.

    Just wanna tow a 2000lb. Trailer up a hill..

    Actually being a 700r4 it's controlled by a cable attached to the throttle linkage. Gotta say it's hard to beat a q-jet for fuel economy. People hate them because they do not understand them, they are not like other carbs so going that route you'd want someone who knows q-jets to help you. But...

    Setting the distributor

    The way the guy does it in the video is cool but I'd make sure the lifters are on the base circle and adjust each valve once, jumping around all Willy nilly can make it easy to mess up. Personally most of the time I do it with the engine running, sure you might get a couple drips but you won't...

    If it were your truck ????

    If it were my truck, I'd start off by checking over the current engine to see if its good enough shape to put an aluminum top end on it, on a budget I'd try speedmaster 396 heads and an airgap dual plane intake and a set of domed pistons for between 9:1 and 10:1, personally id carb it but holley...

    wiper arms

    Cutting them works awesome, I would also drill the spring hole a little higher up so there's more tension on it. I advise that because I had used 20" blades on stock arms but they would chatter in heavy rain and snow. End result worked out great for me and currently Using 22" blades.

    Can a C3500 5.7L 4.10 beat 10 MPG?

    If the intent was keeping the tbi on your 350 what can be done to help with fuel economy is if you ran between 10-12* base timing (I had ran 14* n/a but seeing as you'll be towing try it at a lower advance) and run 305 54lb white and green injectors and use an adjustable fuel pressure regulator...

    Can a C3500 5.7L 4.10 beat 10 MPG?

    Have you ever ran a vacuum gauge? At wot above 3500rpm it's starts pulling vacuum on the 305 tbi (never had a 350)that had the "ultimate tbi mods" and the "salad bowl", by 4000rpm I was seeing 3inhg. Sure I only filled till the nozzle shut off (like everyone else), but I went to the same pump...

    Can a C3500 5.7L 4.10 beat 10 MPG?

    Agree to disagree lol thats just what I've found in my case. from day 1 it got 10mpg and it didn't matter how you drove it or what gears or if it had a little boost, I even had a 454 tbi with the 74lb injectors on it and that didn't change the mpg either. (i figured any one of those things...

    Can a C3500 5.7L 4.10 beat 10 MPG?

    It's the tbi holding you back. I had a 305tbi w/ 4l60e, 3.08 and got 10mpg if you were easy on it or hard on it. Swapped in 3.73 (about this time I got another daily so thought what the heck) still got 10mpg. Strapped on a supercharger and crammed about 7psi into the tired engine, still 10mpg...

    Ardent Fabrication Autocross Truck

    Nice love the build, personally I run an auburn conical style locker and love it! No complaints what so ever and it wasn't too bad of a price around $450 I think

    exhaust help please

    Say what you like but the set up I'm running changed little by little from when I got the truck to now and each being better and better sound, started with a flowmaster 40 single 3 in dual 2.5 out cat back kit with the cat gutted when I got it. First thing I changed was swap the 3" single for a...

    Any guys towing with a 1500 5 speed anymore?

    Also when doing this I used 06 gm 2500hd 6.0 studs off rockauto as they have a pilot and about 1/4" more threads which I recommend for a few reasons, first its good to use new hardware, second more thread engagement especially for aluminum rim's, third the pilot helps a lot with spinning on lug...

    Any guys towing with a 1500 5 speed anymore?

    Not necessarily. I've taken 6bolt axles and carefully welded shut the existing holes and drilled the 5bolt pattern. If you do this you need to get or make a special drill bit that measures .600", I used a 5/8 bit and ground it down. You will need a way of indexing so your bolt pattern is dead...

    Noob here with a 91 rclb

    Q-jet 750 I have a 94 that I swapped to a nv3500 and with in the week the tbi motor kicked the first bucket when a rod bearing decided to jump on top of the other... ended up getting an entire running 84 engine and swapped it in, pulled most of the wire harness off, only kept the wires for...

    Air intake?

    Never could get my data logger to work properly and I drilled a 4" hole into the rad support so the air comes from behind the grill, a scoop from the opening in the grill would make it work even better

    Intake Manifold Question.

    I've put a 4 barrel manifold on and then used the 454 tbi adapter and ran no egr without issues. I did that because I had planned on eventually going to a carb.
