    Wheels and tires

    Suggest you go to the Riviera forum on this website. This has been discussed a number of times and is actually quite tricky. The folks who've done it can fill you in.

    Roadworthyness of 32 Chrysler 6?

    I think this car would cruise at 50-55 if the engine was rebabbited during restoration, provided the rear axle ratio is in the 4.0-to-1 range.

    Dry/Wet Compression Test

    Please help interpret the dry/wet compression test results for my tow vehicle, an '09 Ford V10 F350, with 9.2-to-1 compression ratio with 95,000 miles. It has developed a smoking issue upon startup, but this may be associated with a recent oil change to synthetic oil, from mineral oil, 500 miles ago. Runs smoothly and strongly. A compression check revealed the numbers below. I was surprised by the wide difference between dry & wet, but encouraged by the narrow ranges between cylinders. What do you think? Dry -- 116-120 PSI all cylinders. Wet -- 145-150 PSI all cylinders. Thanks.

    What have you ploughed up

    Friend of mine found a weathered '29 Packard "Sliding Boy" hood ornament in the middle of a field, lying on the ground. There was nothing else around it at all. Landowner had no idea how it had gotten there.

    Who makes connecting rods

    A lot of Duesenbergs are now running modern Carillo rods. Regarding Locomobile, I have one spare rod for my '19 Model 48.

    Battery disconnect switch, yes or no?

    If you do install a battery switch, check the amp ratings and choose one of the higher-amp options. A starter draws a lot of amps. There are a number of different ratings available. And yes, the switches do need to be replaced occasionally, and sometimes the connections cleaned up.

    DIY Cylinder Reboring

    Back in the 1960s an old-time mechanic told me that there were ratchet-type tools available in the 1930s that could be used to resurface crankshaft rod journals with the engine in the car and the crankshaft in the engine.
  9. Two other things I experienced with a 425 in a 1966 Riviera back in the day. A rocker arm broke one time when the car had about 70,000 miles on it, creating a tapping sound. I pulled the rocker arm shaft off and replaced the broken rocker. Also, back when we were running leaded gasoline, the 425 had a tendency to "carbon up," as we used to call it. It would develop pre-ignition, and occasionally a piece of carbon would break loose and create a tapping noise. The solution was to pour a thin stream of Marvel Mystery Oil down the carburetor while applying enough throttle to keep the car running. Then let the car sit overnight to allow the Mystery Oil to soak the carbon buildup on the backside of the valves. Next morning, start it up and take it out on the highway and "blow it out" by running at high speed. It worked several times like an instant tune-up, curing both the pre-ignition and the tapping noise. I don't know that this is necessary anymore given our lead-free gasoline containing ethanol, which serves as a cleaning agent.

    Evans waterless coolant

    I think I remember reading similar stories on this forum about cars running hotter with this stuff.
  11. Wow -- this really would have been a nice car in its original form.
  12. There were about a half-dozen cars from Texas on the recent Glidden Tour in Twin Falls, Idaho, and we had a great time. The scenery was unbelievable, and included deserts, mountains, river valleys, the Snake River gorge, Shoshone Falls, City of Rocks, Craters of the Moon, Mt. Harrison, and some of the richest agricultural land found anywhere (thanks to irrigation water from the Snake). Some of the roads we drove had little traffic on them, and the weather was perfect -- clear with temperatures in the 70s. There were small, rustic towns with delightful home-spun cafes, contrasted with the incredible Sun Valley Lodge with its 1930s-vintage style and luxury. I'll post a few pictures in a week or two.

    That's one beautiful car.

    Wanted: 1937-38 DeSoto

    Agree -- that Imperial is beautiful.

    Pre War Cars - how fast is fast?

    Agree on capability of supercharged Auburns with dual ratio. I cruise mine at 70 at 2,400 rpm.
