Hot-Rod Newport Progress

Okay, so it's 88 degrees Fahrenheit up here in my writing office, so I decided to go work on the Newport a bit. I mean, if you're already boiling to death and can't think straight to write, you might as well go outside where it's even hotter and do some manual labor, right? I think my reasoning went something like that.

I have a wonderful air-conditioner-slash-dehumifier in the garage, and it displays a temperature readout. Normally - that is, in temps below 100 - it does a great job cooling the garage, and even allows me to cool my back with the door open. But not today. Here's what it looked like just a few minutes after opening the garage door:


It's so hot outside right now that I watched a grackle hide in the shade of a lawn chair, mouth gaping, as it occasionally took a dip in the birdbath. In case you're wondering, I've given up on working outside. Thus this post instead of actually making more progress.

Here's what I finished installing - the new EFI fuel pump with pre- and post-filters, high-pressure fuel line, and wiring to fill the new MSD Atomic EFI system:


Yes, it's still in my driveway. Foolish me, I pulled the carburetor, old distributor, and associated parts a while back, WHILE IT WAS STILL OUTSIDE. In the lovely spring weather, that seemed like a good idea. And I thought I'd have the EFI system installed before the start of the Science Fiction Summer program. Ha. I should always remember the formula for how long something takes to do compared to the estimated time: "Double it and add 30." Now I'm dehydrated, dying of heat, covered in mosquito bites, and bruised from lying on pebbled in the driveway. Someone please remind me that I like to do this stuff.

Other under-car hijinks included installing this collector-reducer onto the header. Note the newly installed oxygen sensor that tells the EFI system how much oxygen and unburned gasoline is in the exhaust:


Here's the injector setup mostly installed on the engine; the sensor array and computer reside beneath the finned cover that says MSD. You can also see the primary computer installed on the far side of the engine compartment, the red box near the top of the photo. The new digitally controlled distributor is the red part on the right with red spark-plug wires coming out of it:


From the driver's side; nice-looking machine, isn't it? The red cylinder in front of it is the high-energy coil, and you can see the newly installed distributor behind it. The distributor is necessary because the old one kept losing timing, even with the old optical sensor; on top of that, it'll also be awesome because now I'll be able to plot a digital ignition curve via the MSD computer interface: No more crappy idling, pinging, or sluggishness!


Why EFI? Because a carburetor is nothing but irritation is why. If you haven't had to deal with one, congratulations! After - what, two years? - of poor starts, regular adjustments, and other tinkering, I got fed up with the carb. EFI provides better fuel mileage, easy starting, better throttle response, precision tuning, usually more horsepower and torque, and many more benefits. I hope to let you know how it runs in a week or two!
