Light my fire
I already wrote about the carburetion previously, but having fuel and air mixed in desired mixture won't get you going unless you have something to ignite the mixture at correct time. As for my ignition needs I was considering two options. Electric or points type ignition. While electric one offers better spark and more accurate timing with basically zero maintenance, the beauty of mechanical "points type" breaker system is in the simplicity. It is safe to say that if you have spare points and screw driver handy nothing can stop you. Ok, maybe a spare coil would be a good idea too, but coil failure is so rare and unlike event that I wouldn't worry about that too much. Also, electric systems can be picky about the coil and you must run a certain type of coil or you may get bad spark quality or even burned ignition controller, but points type ignition can usually run almost any type of coil out there and still get you where you're going. Of course it matters what you have in there in means of spark energy and duration and so on, but in case of emergency you can basically use whatever you can find.
Signet ain't high performance car. It ain't pollution controlled neither. Hotter spark of electric ignition wouldn't hurt, but probably wouldn't offer any noticeable different in performance nor fuel economy. Just some less maintenance that comes in expense of simplicity. It wasn't clear to me in beginning and I was really considering these two options, but the simplicity won, again. Points will get the job done just fine and offers if not better reliability, but ultimately simple construction that I can always fix no matter what's the problem. Important thing that counts with this car, so I went down the points line. Also, points ignition is not sensitive for failures in your charging system like fluctuating/too high battery voltage or busted diode in alternator that can create alternative current in you electric system. While these kinds of failures can easily interrupt or destroy electric ignition systems, the points type won't mind at all.
For my cooling needs I had a huge aluminum left over radiator (brand new though!!) from some of my previous projects. Actually a ´65 Valiant with blown big block. I never completed that car with the 572cid big block, but ran a lot with different small blocks, including blown 360cid. It was a nice car, but I sold it some years ago. Anyways, the radiator that I have for signet was originally bought to cool down forged induction big block. It is definitely large enough to keep signet's 225 cool even in hottest Thai summer day. As you probably know, I'll be heading to Thailand with this car some day, so there will be weather conditions on the way that are tough for cars cooling systems. In this case, I'm not expecting any overheating problems though:D
Another thing to keep cool in this car is the transmission. Automatic transmissions are known to create some waste heat, always. The torque converter inside automatic transmission always create some waste heat and that heat must be dissipated somewhere somehow in order to keep the transmission fluid temperatures in acceptable level. My pick for this job is a aluminum transmission cooler, actually a brand new left over piece from that very same '65 like the radiator! It should be large enough, but I'm still planning to install transmission temperature gauge in the dash so I can keep my eye on the tranny temps. Just to make sure I won't burn it.
One more thing related to cooling system is actually doing something very opposite. Instead of trying to keep something cool, it is heating up something! Yes, the cabin heater. It is related cooling system because it uses the engines waste heat to heat up the cabin. It has a small "radiator" inside where the engine coolant is circulated which in turns heat the air travelling trough it. I probably won't need the heater in my destination, but there is places on the way where I most likely will... I'm using Signets original cabin heater with no modification. These cars came with pretty good heater from factory and with my 400 000 kilometer experience of year round driving with A-body Mopar right here in Scandinavia I can tell that the heater is just about as good as it ever needs to be...
Below is a slide show about the cooling system:)
Oookay, and now all the rest. Starter motor, alternator and some other stuff. Cooling system wasn't really an accessories at all, but I included in this post anyways. It's something alike anyways... I also included fuel line in this post, but it ain't engine accessory neither. But the engine won't run without one, sooo, I included it as well. I made it out of same copper tubing that I used for transmission cooler lines. Some folks don't like to use copper tubing in their cars because copper act as cathode for iron (=steel= your cars body) which will become anode causing it to rust in points where the copper touches steel. However, that can be easily fixed using rubber or plastic isolation in mounting points. I've been using copper transmission lines and fuel lines in my cars and never faced a single problem. Good sides of copper is that it is very easy to work with, it withstand all possible chemicals you will ever need to use in your car and it don't corrode so it basically lasts forever. Make your lines out of copper and you will never need to do it again. Also, it's affordable and easily available. Plastic would also work for fuel lines and it is (of course) cheaper and lighter than copper, but I leave it for tuning guys.
