    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...

    Front differential vent hose

    You want it up high enough to not allow water to enter when you are doing deep puddle/river/pond crossings. Some relocate them even higher.

    Off-road bumper ??

    Well- I got my ORD bumper and now it doesn't bolt on. The bumper itself has 4 holes drilled into it per side: However the frame only has 3 holes. And out of all those holes in the frame and the bumper only ONE will line up. And that is the larger slotted hole in the frame for the tow hook...

    Long bed camper shell

    I had a topper just like that on my old truck 20 years ago.

    1977 K5 3000$ OBO!!

    For some reason those seemed to be popular once upon a time. My truck had one when I bought it. I got rid of it.

    How much whp am I gonna have in my lifted truck

    I'm not a fan of horsepower ratings on trucks or towing vehicles. Did he say how much torque? Any low end torque? Unless you are planning on running it at a higher RPM where all your horsepower is, who cares? I'm running 37s with 4.10s. The truck used to feel really quick with my 383 (444...

    Think I need new springs? shocks? ROUGH RIDE

    You should look into getting new bumpstops for the front suspension. That factory one isn't very flexible anymore. They make some nice squishy aftermarket ones to replace it. And if you put a lift on it you should extend the bump stop down a bit, or buy a longer bumpstop. Don't want your springs...

    Question, are all full size square body Blazers referred to as K5 ?

    It matched the dash- looked like this. (not my Jimmy)

    Question, are all full size square body Blazers referred to as K5 ?

    I had a 1986 GMC Jimmy. The only badging on the outside was GMC, Jimmy and then near the taillights it said Sierra Classic. The older ones just said GMC Jimmy also. No K emblem.

    Ultimate Adventure 2020

    I have been part of quite a few different automotive groups thru the years. I've always had some sort of square. 2 blazers, a K10 and a K20. Have always went off in search of trails to see what they can do. I bought a ZR2 in 2001 to replace my K10. Had some advantages, but just missed the old...

    wheelin' it

    In a nutshell someone explained to me once that a crossover steering bar is roughly 3 times longer than that short stock draglink for steering. The longer something is the less it will be affected by angles. And you will get some angles with ORD suspension that has up to 14" of travel. Maybe...
