I don't know how he does it, but my friend Brad Allen has put together some very rare footage of our precious
Advance Design trucks and allowed us to present them to you. You will find these slide-shows throughout the site.
Some of them are very instructional and all of them are quite interesting! I hope you have as much fun watching
as I do!
The idea was to explain in detail the steps it takes to properly rebuild a 1959 235 6 Cylinder Engine. From start to finish, this article goes through
every aspect of a rebuild, from tear-down, to the engine shops work, to rebuilding each subsystem, right through to engine adjustment and run-up. This
article was completed in the Summer of 2015 with really great results. If you have engine questions, there is a distinct possibility the answers are in
This system monitors your most critical systems on your vintage vehicle in a similar way your modern vehicles take for granted. This system is a proper Redundant backup system for your gauges providing you with bright LED lights that alert you of a catastrophic failure. But we didn't stop there! We also provided an Audible Alarm for the most two important systems, water temperature and oil pressure. Rather than scanning your gauges and hoping you catch the failure in time, let the vehicle tell YOU when it needs urgent attention! Not convinced?
Most of our vintage vehicles have external oil lines for connecting external oil filter cannisters, the mechanical oil pressure gauge, etc. These rubber hoses tend to dry rot over time. If you were driving down the road at normal speed and a hose were to break, you are spewing motor oil all over the highway at a rate of about 15 seconds per quart. This gives you about 90 seconds to shut down the motor and coast to a stop. That is not after you SEE it, it's right away! Hopefully you stare at your oil pressure gauge all the time. We all know better of course. You have the responsibility of driving to contend with.
This system is a fully redundant backup system for your gauges meaning it uses no part of the current gauge system. This gives you the peace of mind in knowing when an Audible alarm sounds PROMPTING you to look at the gauges, the answer will become immediately clear. Engine Rebuilding is a very expensive and involved process and in our local area, the cost is at least $2,000 not including the inconvenience. Protect your investment! With the cost being about 10% of that, this easy to install system will give you the peace of mind to actually enjoy your Vintage Ride!

I was trying to help someone the other day in explaining the advantages of HEI, but it always makes me feel like I am being self serving since I designed one specifically for our engines that uses your stock Distributor and works just as GM designed it. So, I searched the Internet looking for a decent, very accurate article and found the perfect one. Here it is from one of the most respected resources out there:
One of the other issues that I get asked a lot is "What is the difference between GM HEI and Pertronix?" Despite what the advertisements for Pertronix say, the units they sell are strictly 'Points Replacement' units. They have no artificial intelligence behind them. Pertronix units go inside the Distributor and replace the Points and Condenser. They are a great low-budget solution and they work very well. They are easy to install and they really do the job for which they were intended very well. I have heard very few complaints about them. They are popular because they are relatively inexpensive, remove the points and condenser from the equation replacing them with no moving parts to wear out, and another reason to like them is they take away the dwell issues of Points and the problem of Jitter caused from the Distributor shaft wear over time. Your engine WILL run better with a Pertronix unit instead of Points.
The difference between Pertronix and GM HEI is yet even greater! GM HEI has artificial intelligence that makes it leaps and bounds better from a logical perspective. The GM HEI has an Electronic Ignition Module. This Module, although quaint by today's standards, was the grandfather of our modern electronic control modules which are considered on-board computer systems. The GM HEI Module gives the system its ability to self adjust the dwell based on Engine RPM. Its secondary function is to speed up dramatically the ramp and fire circuit to 3.6 milliseconds which enabled much faster coil response. What this means is, we can use hotter coils since we are no longer limited to 12,000 volts, which is about the maximum a points system has time for in one complete cycle. This means a more complete burn of leaner fuel mixtures. It also has a current control circuit that keeps the amperage of the entire ignition system down to 5.5 amps.
Aside from the above, the GM HEI System removed the resistor circuit from the mix. This means no more reducing the points and condenser down to 6 volts which was the practice right up until GM HEI was introduced in 1975. The Resistor Circuit is what that big paint melting ballast resistor that is on your firewall was used for. By transferring half of the available power to heat, Delco was able to keep the 6 volt production line going clear into the 1970's! The GM HEI system uses no resistors and with transistorized current control, as stated earlier, keeps the current limited to 5.5 amps. In fact, it craves the full 12 volts of power and is much happier with a 45,000 volt, .7 ohm coil with the spark plugs gapped to .045. as stated in the above article, it really is a very well engineered system. So, no matter where you get your GM HEI System, plan on a much more precise and much hotter spark, extra power in 3rd or 4th gear, and a much happier Engine!
The Plus is, we use the Stock Distributor you already have! To make it even better, we make no permanent modifications to your vintage distributor.
The GM HEI system is well known for its hotter spark, more efficient burn of today's gas formulas, and a cleaner, smoother running engine. As our
friend, Jim Linder, a renowned Ignition Specialist puts it: "The HEI as built by GM could very well be the best overall ignition system out there ever.
It has a varying dwell based on engine RPM and a ramp and fire circuit using 3.6 ms and 5.5 amps output with current control." If you have converted
to a 12 volt system, you are on your way! Check out the fuel mileage tests and all of the particulars! Very exciting!
Grandma always had a 3 on the Tree in her grocery getter, but Grandpa drove real trucks so he went with 4 on the floor! In our Feature Article we will show a brand new solution that puts the 3 speed shifter exactly where the original 4 speed comes up out of the floor making the truck look like a stock 4 speed. It may not be the Higgs Boson, but it really revolutionizes the way we look at the vintage 3 speed transmission...
The Heater System in these trucks can be one of the most neglected systems both from a maintenance and an engineering perspective. If you have upgraded
to a 12 volt power system, it may very well need some TLC before firing up the heat for the Winter.

What this site is all about is documenting How-To articles to help you finish your Truck Restoration with full confidence. Over the years we have accumulated a few things to help you. Most of these articles were written upon request by kind and knowledgeable people who freely give their time for an worthy cause. If you know something and wish to share it, check out the How-To pages and maybe they will prompt you to write what you know, and others would certainly appreciate.
The How-To section is broken up in sections to make navigation easier. We have a pretty extensive
Engine Archive with just about every aspect of your vintage engine covered.
The Driveline Archive includes some very rare and important Borg Warner
R10 Overdrive Transmission Documents along with a few other Driveline related articles. We would love to have more in this section so if you know something,
please share! The Chassis and Sheetmetal Archive has documents from how
to Re-Rivet your Frame to how to Cut and Install Bed Wood. This section could use some help as well. Don't be shy! Writing an article doesn't take that
much time and look at what you are doing for others! The Misc. Systems Archive
is getting stronger and includes Electrical systems so has become very popular. There is alot of stuff in these documents that is new or not previously
looked entirely into. We are in the middle of researching some of the more nuanced issues so check back often. The most fun for me is to add things to the
Shop Systems Archive. There just isn't enough time in the day to look into all
of the Shop helpers out there. Anyone with similar interests, write up a Shop Tip

We decided to engineer a bracket system for all styles and types of oil systems so there is something for everyone. For both Bypass and Full Flow Oil
Filtration, these Spin-On Adapters make changing oil just a little easier. In addition, they add a little Style using Stainless Braided Hoses. Great
for any 216/235/261.
The 216/235/261 era was the last to NOT have PCV as a standard system. We know now how important evacuating crankcase gases is to the longevity of your engine. This is a simple weekend project that will keep your engine internals cleaner. It won't bring about World Peace or anything, but it's not for the lack of trying!
If you spend much time on Forums, you know how it works. 90% of the information you get is from the Peanut Gallery. People who like to talk and are short on actually doing the work of investigating the issues are usually the most vocal. Yet, it would be very difficult to live without them. This is because for every 100 idiots, there are about five people who really know what they are doing. So we sift through the posts and try to make sense out of the answers posted. This leaves us with the possibility of making poor choices from the poor answers we received on any given day.
To stop this dead in its tracks, we have a Forum where conjecture that is not based on actual math and science isn't acceptable and thus deleted as soon as we see it. Participants understand the importance of explaining in detail WHY and exactly HOW. So, we are very short on Participants! Not alot of traffic in the Forums. Those of you who are hesitating, understand this is not the normal Forum system, so flaming and the normal dynamic that we all have to put up with everywhere else will not be tolerated here. If you are looking for THE answer to your specific problem without the time wasting BS that is just an integral part of any Forum system, then post your question and expect to be treated with kindness and understanding each and every time.
The Think Tank is another unique feature available to everyone. If you have an inventive spirit and wish to design a solution to any problem pertaining to our vintage vehicles, our shops, or anything surrounding restoration, post your idea and expect others to help you accomplish your goal. This particular area of the Forums is for Research and Development which often times is not very pretty! Anyone with R & D experience can attest to the trial and error nature of it all. Upload all the pictures, diagrams, movies, links, anything you need right into the Forum. No hosting sites necessary.
We are so much stronger as a society when everyone participates, so please stop by from time to time and make sure to critique whatever you feel we need to work on. Thanks in advance for making this project a success! There are several projects just waiting for participants, so please check them out. We are always looking for new ideas, so please tell us your ideas! Check it out at TechNet Forums!
