    Keep it original?

    Also, out of curiosity, does avgas have enough/too much lead to be beneficial or harmful?

    Keep it original?

    Appreciate all the feedback! It is a 23k mile car that has been passed down through three generations. Everything is original on it except for the usual wear, and tune up items, with the exception of some of the a/c parts that needed to be replaced to convert over to 134a. Here are some photos...

    Keep it original?

    So I have this 73 Grande with 23k original miles, and as many of you know, these are 351c engines are turds with all the smog restrictions in place (California car). As a project, I've been tempted to pull the heads to have a machine shop install hardened valve seats. Of course, that would be a...

    What is the restrictor air door vacuum motor

    That is some type of dope they use at the factory to seal the hole around the temperature probe for the a/c cutoff switch. I used plumbers putty when I resealed my heater box.

    What is the restrictor air door vacuum motor

    Not sure if this helps you out at all, but I snapped a couple of pictures before I removed the heater box...

    A/C Compressor Removal

    Due to a heater core leak, I was forced to disconnect the A/C lines going to the heater box. I figured this would be a good time to get the A/C back in working order. I ordered all new hoses, and other parts needed to retrofit the system to R134. Keep in mind i'm going for originality with this...

    New Grande Pics

    Thanks for all the great feedback! The wheels really brought the car together, and made it all look in proportion. The factory 14" steel wheels with original hubcaps just weren't doing it. Other than the wheels, and a pertronix ignition, everything is original or oem. That odometer is reading...

    New Grande Pics

    Finally got around to getting some pics of my 73 Grande while it was out of the garage. There are a few things left to take care of, but soon she'll have working air, and fully road worthy!

    Timing adjustment

    Thanks for all the feedback. Everything is stock on the car so I just went with the Ignitor I module. The car does not have a tach, but if you can run resisted supply to the coil with the Ignitor I, I'll just leave it alone. I did purchase the 1.5 ohm coil to install with the module as well. I...

    Timing adjustment

    I read through the pertronix instructions before I installed the unit, but iii checked the voltage while it was running, and I guess that throws off the volt meter. I checked it in the KOEO position, and I was getting 7 volts at the coil, so there is a resistor. Would you happen to know where...

    Timing adjustment

    I wasn't aware that they had a resistor on that year. I'm getting 12 volts at the coil so I didn't even think about it. I don't think that would throw off the timing mark though. I got the car up on ramps today so I could get a close look at the harmonic balancer, and it looks in great shape...

    Timing adjustment

    I went to check the timing on my 73 Grande after installing a Pertronix ignition module, and noticed the timing was way off (30+ degrees advanced). I retarded the timing to 8 BTDC, and the car ran like crap. When I went to restart it, the engine backfired into the exhaust so i know the timing...

    EGR Spacer gave up the ghost...

    Thanks for the positive feedback! You cant really see it in the picture, but under the pvc line, there is a little pitting and erosion on the manifold gasket surface. I'm not sure if its going to seal properly or not. It's amazing that spacer rotted out after only 23k miles, but I guess a...
