    Mileage on 5.7 vortec

    Hello all, I just got back from driving 600 miles for a little road trip. I figured now would be a good time to see what my mileage is on the highway. I just used DashCommand for it and it tracked it well with graphs and everything. The results were less than desirable though. I was about 8mpg...

    Autotrac delete (tcase swap?)

    I dont know if it would affect anything but everytime I go into 4wd I gotta be in neutral. Then I go back into drive and carry on about my day. Maybe you have mismatched gears in the diffs? lol probably not much help just my random thoughts

    Choices to make, experience needed.

    I'll x2 with the 6.0 and gearing. My truck came stock with 3.73 and it was up'ed to 4.10's when I get my new 33's. it is definitely a noticeable difference and I recommend it. Coupled with the 6.0 and a tune and you'll be the little engine that could.

    Please help

    Holy crap. Talk about a parts cannon. It sounds electrical to me since you've replaced literally everything else. check your wiring leading to the actuator. only money I'm betting you're going to have the spend is some tape to fix the short you have

    O2 sensor help

    I'm thinking about getting 2.5in duals with an H pipe and a couple glasspacks in under my truck. I'm not worries about the rear o2's because I'm just gonna tune those out. My question is, does the exhaust shop just add bungs for the front o2 sensors? I thought those are the ones that affect A/F...

    1996 350 vortec.idle and dies

    Try unplugging your MAF sensor to see if it stops dying. Test fuel pressure. Test sensors on the intake(idle air control valve) then make sure you get spark

    New Twist on the 0411 Vortec 454 swap!?!?

    If you're made of money and can drop that much for a factory harness more power to ya. IF it were me I would go pull a harness myself from a yard or from someone on craigslist. That way you learn where things connect to and how they're routed and you save literally hundreds of dollars on a...

    Would you ditch this truck, do engine swap, or swap the head gasket?

    Your situation sounds alot like mine was when I bought my truck. It's a 98 K2500 with the 350. The truck ran great when I got it until I looked at the oil in the first oil change. Chocolate milk. I thought it was a head gasket so I youtubed and read books and joined this forum to figure out...

    Thick smoke at tailpipe

    I did a compression test and was getting 160 psi in all cylinders. I did put some painted headers on and they did smoke some when it first started up but then it just kept coming out of the tailpipe nonstop

    Thick smoke at tailpipe

    I just put a used engine in my truck to get it back on it's feet and it fired right up. Only problem is it's drinking oil and I get pretty thick smoke at my tailpipe. Before I put the engine in I replaced all the gaskets and seals except for the rear main and valve seals. This makes me think...

    What is this vacuum port

    Yeah no valve on my heater line. I did just put this engine in that came off a 99 Tahoe so that should explain it. Good to know I just cap it off. I appreciate it.

    It has one wire and it gets bolted somewhere. It's the last connector I need to put in but I can't find where it goes

    Does the oil inlet line go into the top fitting of the radiator? I thought it did but I can't remember.

    Must haves for in-truck toolkit

    Piggybacking on the roadside assistance, I have the AAA plus and it's so sweet. Got my truck delivered to my house at 12am 77 miles out of town. Then diagnosed it and towed it to my buddies to work on it the next week. All free.
