    78 K5 Gas Mileage

    I really liked Austria when work sent me twice. Got to spend 6 weeks in Salzburg and then another 6 weeks in Villach. I'd go back in a heartbeat. Really enjoyed everything there.

    Kinda jonesing

    I did make it out on the 17th... was waiting to see if anyone that went posted better pics- no one has. :( It has been around 90 degrees for what seems like a month, and really no rain to speak of. This whole area is bottomless clay. Don't want to be here when it rains. The whole valley in...

    Are “cheap” tires bad?

    I've had "cheap" tires on different vehicles off and on. Usually when buying something they said it was a selling point. "It's got new tires!!!" then you look at them... They have all been safe enough. No blowouts (other than a re-tread in 1990 blowing apart on my old K5). But often I found...

    78 K5 Gas Mileage

    I saw this post last week and made me curious. Last weekend I went on a trail ride with my truck. It was 158 miles round trip. Temp was 80 degrees in the morning and peaked out at 90 degrees in the evening. 26 of those miles were on rough dirt trails with hill climbs and descents. Maximum...

    https://www.offroaddesign.com/blog/post/i-got-some-new-big-tires-what-gears-should-i-put-in-my-axle.html Offroad design had an article about what gearing they used on a bunch of different trucks they have. Basic theme was you needed pretty low gears for trucks with an OD transmission. On...

    That's the best I can do for now. Supposed to be a club run on the 17th. Hopefully it won't be too hot and dusty. Making me think about getting my windows tinted...

    Any good hacks/upgrades you've come up with for our trucks

    I bought a GM performance mini starter years ago. Love it- truck starts easier with less current needed. But I had to modify my flex plate cover for it to fit. Not quite sure why- hadn't heard of others needing to do this. If I remember right it was because my crate engine had a smaller...

    LED Round Headlight Conversion

    The sad thing is how bad the DOT “certified” headlights are. Technically my hella H4 housings are illegal because the have the euro cutoff pattern. However they were used by law enforcement, fire departments, and ambulance for many years because of the superior light pattern. Or the Audi S4 I...

    LED Round Headlight Conversion

    I tried to find the pictures of beam pattern from back when I first installed the hella h4 headlight housings compared to the original sealed beam headlights. Can't find them... There was pretty much no cutoff on the sealed beams. As long as the headlights are properly aimed so far I think they...

    LED Round Headlight Conversion

    Staring into a headlight doesn't tell you much about the bulbs. So here are some pictures of the pattern on my garage door. Ignore how the LED pattern is lower. In my haste to remove the old headlight I mistakenly turned the adjustment screw at the top. I re-aligned them with measurements later...

    LED Round Headlight Conversion

    Yes, the LED is on the left. The LED just installs the same way pretty much as the halogen bulb. Only difference is the little wire keepers that hold it in place need to be maneuvered around the heat sink part of the LED bulb.

    LED Round Headlight Conversion

    I have the Hella H4 7" round glass housings and was using halogen bulbs for quite a while with the LMC headlight relay harness. Worked well, but had to replace relays about once year. Wanted something that would draw less watts and make the relays last longer. A few weeks ago I installed some...

    Master Cylinder Size

    More than likely the brake line size will be different front vs rear, so the threaded connections will be different also. They do make adapters so you can reverse them.

    Kinda jonesing

    That's why I don't live there. At least on purpose. Last year work sent me to Chandler in April. Some of my Arizona friends said it isn't bad in then. I'd like it... Left here and it was snowing. Forecast was supposed to be low 80s. Nope. Record breaking day of 103 when I flew in. I'd leave for...

    Kinda jonesing

    I was supposed to have a trail ride yesterday to go up and over some mountains and see if we could make it thru the deep snowdrifts that hang out there. Trip got cancelled. Few of the guys have cherry orchards and one guys is building a house. Too many things happening- so it was cancelled. And...

    Stock Differential Covers

    If you get an aftermarket cover that it is rounded and has some sweeping curves to it like the stock one I'd think you'd be fine. Don't buy a big square box...

    Vortec Coolant Bypass - Can't you just drill a hole in the head?

    I bought a whole entire crate engine from GM (HT383) after my 400 started drinking oil after putting new heads on it. I wanted something with a roller camshaft after I found my old 400 had some lobes flattened when I bought it. I did a TON of research and thought I made the best decision in the...

    Vortec Coolant Bypass - Can't you just drill a hole in the head?

    From what I can remember (hey- it was back in 2014) the ports were different size. The forward facing one was too small for the temp sensor they sent me.

    Vortec Coolant Bypass - Can't you just drill a hole in the head?

    Drilling the head should work- I'd just be too chicken. And the coolant bypass can be difficult depending on what water pump and what intake manifold you have. When I first tried the hose bypass the GM performance intake manifold made it very difficult to hook everything up. (location and size...

    Vortec Coolant Bypass - Can't you just drill a hole in the head?

    Well- at least for myself drilling into a brand new head and being unsure of measurements is enough of a deterrent. Cheaper and easier to run a bypass hose or just drill some holes in a $10 thermostat.

    Stock Differential Covers

    My '77 K20's D44 stock diff cover has a fill port in it. When I bought an aftermarket Riddler off road protection cover it also had a fill plug- but was probably 2" higher than stock? I took measurements when I installed it and then made sure I didn't over fill it. Kinda sucks, because now to...

    1981 1500 5.3 LM7 Swap?

    http://tildenmotorsports.com/products/take-out-engines.html Might be up your alley. They sell used LS engines along with a wiring harness and the computer. Haven't used them, but seen them used a lot on different car shows. As much "hate" as the LS swaps get, something to be said about just...
