    83 K20 GEAR RATIO

    G'mornin y'all! So, after some calculatin' this morning, I'm pretty sure I have 4.56 gears in her. Going out to confirm later this morning, but it's just too danged cold right now. I'm 99% sure the original owner (late father in law), never had anything modified on the truck, but it was used...

    Order of upgrades

    G'mornin y'all! So, sometime last year (or year before? lol) I picked up a '97 880 engine, with the intention of doing a bit of top end work to it (heads, cam, intake, etc...), and slapping it in my 83 K20. Pretty decent deal, 200 bones for a just about complete engine. Pulled the heads, and...

    Interesting Oil Pressure Indications

    G'mornin y'all! Bone stock '83 350 with about 65K miles. Family owned since new, has never been opened up (relevant later). A while back I had a bad oil pressure gauge (resistor), and upon replacement of both the gauge and new sending unit, the pressure seemed high. Like in excess of 60 at...

    Quadrajet getting vacuum at ported vacuum

    G'mornin y'all! Been a long minute since I've had any time to tinker, but finally got some. Ol' Blue is running great, but me being me, I wanted to check timing. Like I said, tinkering. I've been running my dizzy advance ported, and she seems to like it. With the vacuum disconnected, I have...

    Stock 350 getting hot, but only on the highway with AC on

    Okay, this makes no sense to me. I can cruise around all day in this heat, city or highway, no problem. Temp gauge is 180° or so consistently. I can turn on the A/C and cruise around city driving, no problem. Here's the issue. When I hit the highway and turn on the A/C, the temp climbs to...

    Misc gauges

    I have a few gauges that I'd like to pass on. I believe they all work, but I got tired of fiddlin' with them, and went with a Dakota VHX system. The oil pressure and temp gauge (with needles) have orange resistors on the back. Not sure if they're good, so I might ohm them out later. Anyway...

    Oil Fill

    This is going to be the dumbest thing I've ever written. So far. Been gone for a while (work), but before I left, I threw an oil change on my '83 K20. Then got ambitious, and threw on some of the chrome bling that my wife picked up a while ago as a gift. Part of that package were valve...

    1983-ish 4X4 Front Dog Dish Hub Cap

    Looking for a front dog dish hub for my '83 K20. See image below (12" flavor): Thanks!

    Coolant Temperature sensor

    A while back, I was trying to get my temp gauge working quickly (trying to get her back home), but wasn't having any luck, so I installed a cheapo aftermarket kit from the local parts store, and all was good (other than her getting hot on the highway when I run the A/C). Now that I've got a few...

    Aftermarket aluminum intake worth it?

    Okay, let's go ahead and get this out of the way. I'm an idiot. There. Done. I said it. So, six months ago, I purchased an intake. Specifically, an Edelbrock 2701 intake. I shipped it to a work site, opened it up, and oooh'd and aaaah'd at the finish. I packed it back up, and dropped it...

    Upgrade order

    Finally got some time to tinker these last few days. Wife worked on restoring the dash while I de-smogged and added headers. Also put in a new headliner! So with the headers installed, she seems to have a touch more grunt, but I always knew that I wanted to do a bit more for her. I'm...

    Double Hump thoughts:

    Found a set of rebuilt double hump heads (casting # 3782461) that I can pick up for 400 bones. I've been toying the idea of getting a better flowing set of heads to go with a RV torque cam for my 83 K20, and thought this might fit the bill. What say y'all?

    Lost an ignition module. Why?

    So, I got the headers installed and welded out. AWESOME! Lost an ignition module on the way home from the exhaust shop. Super NOT awesome. I checked voltage at the dizzy. All good. I thought it was the coil. It was hot. And when I say hot, like the surface of the sun hot. I figured it...

    NECESSARY Q-jet vacuum lines needed

    Finally got some time to tinker. Got some headers installed (removed the air pump) and was moving on to cleaning up the 3.641 miles of vacuum lines up on the intake. I know I need vacuum advance, brakes, cruise (when I get around to troubleshooting that), but what else do I need? There seems...

    Exhaust Manifold Removal for Headers Install Questions

    Hey folks!! It's been a while since I've been on the forums. I've been busier than you know what, and haven't had a damned minute to tinker with my 83 K20 at all these last months. BUT, I've got a few days, so I thought I'd drop the headers in. Might even tackle the intake while I'm at it...

    Have to store outside. Truck Cover?

    Anyone have any suggestions on a quality cover that I can use for my '83 K20? Trying to find a place to store her inside, but no luck thus far. She's a beaut, and I hate the though of leaving her in the elements unprotected. Thanks!

    1983 K20 - Pep her up or leave her alone??

    Okay, so my '83 K20 is amazing. The wife and I love driving her. Heck, it was her late daddy's rig, and it's the truck she learned to drive a ton of years ago, so it makes sense. Plus, she looks amazing and drives just like you'd expect. :) When I first learned I was going to be...

    A/C System Leaks

    Okay folks, I did a stupid. I knew I was doing it wrong at the time too, but impatience got the better of me... So, the '83 came with factory air, and I decided, at the behest of my better half to see if it was serviceable. Here's what I did: Checked for pressure. Zero. Not a pip...

    I-Talian Tune UP

    So, I had gotten ye old '83 running pretty decent. Driving her everyday, 13 miles each way to work. Getting a little heat soak after about 15 minutes when I'd run into the grocery store, but nothing I couldn't live with. Three days ago, I noticed she wasn't running at optimum. Seemed like a...

    Gauge resistors or Complete Gauges

    Looking for the resistors on the back of both the Voltmeter and Temperature Gauge (mine are both open..). Or the complete gauge, that would be fine too. Thanks!

    Temperature Gauge Open Resistor

    So, my gauge has been reading high, meaning it maxes out on startup first thing in the morning. It seems to move a bit as the engine warms, but obviously somethings wrong here. I ohm'd out the sending unit, and checked for grounds, but all was good. Decided to pull the dash, and found that...

    Need Shocks...and maybe new kidneys

    So, I've got my '83 K20 up at running, and am temporarily running it as my DD (I left my true DD in KS, I'll pick up someday ;) ). First , I love driving this thing!! Definitely a trip down memory lane when I get behind the wheel! That being said, as I drive her more and more, and get some...

    All gauges are wonky...

    Just getting my new (to me) 83 K20 moving again, and I'm needing a bit of help regarding my gauges. Here's what I have: Volt meter - Needle never moves from 0 Oil pressure - Needle never returns to 0, only moves a tiny bit (between 60-65) Temperature - Needle never returns to 0, indicated...

    Header/Exhaust thoughts

    So, I've got a pretty significant exhaust manifold leak (#2, I can feel it lol), as well as an exhaust leak at the muffler itself. Looks like it might have been drug over a stump or something similar, the mufflers bent and crooked. So....I'm thinking that if I'm going to go to the trouble of...

    Rebuild Auto Hubs or Replace with Manual?

    In my 83 K20, it feels like I'm getting some significant drag when I let off the gas at any speed above 45 mph. I've confirmed that the transfer case is not in anything other than 2H, but when I try to turn the transfer case driveshaft, it feels 'notchy'. I've double checked the brakes, and...
