Please expedite adding 4-hole metallized gaskets to take up the space between the flanges on the downpipe and the exhaust manifold. Olson's Gaskets would be the first space I'd try.

Let me try to address the question even though my oldest car is a 1918, outside the brass era and not eligible for HCCA *national* tours. I belong to HCCA national as required to participate in three separate HCCA Regional Groups (RG)/Affiliated Registries. A key point is that *regional* HCCA activities often allow post-brass but still pre-WW2 vehicles, sometimes in limited numbers so as not to overwhelm the brass car drivers' need for slower tours. For each event, need for a trailer depends on the capabilities and limitations of your car, and locations of yourself and the start/end points of the event. There are also separate tours limited to one-cyl, 2-cyl, and smaller 4-cyl cars. It's a smorgasbord! * Bay Area Horseless Carriage Club (BAHCC), a RG, was founded in 1950 and is based in my local area. It is the type of club I grew up with 60 years ago: monthly meetings (some now on Zoom), annual holiday party, July 4 parade with following BBQ at a member's home, monthly half-day hands-on tech sessions at a member's home March-November, monthly one-day tours in the local area March thru November, including a day-after-Thanksgiving Pilgrim's Picnic in which we bring our own TG leftovers plus desserts to share (if inclement weather, we meet at a member's collection). * South Bay Vintage Touring Club, a RG better known as Nickel Age Touring Club (we had to drop 'nickel' as already taken when signing on with HCCA as national org), which does one annual 3-4-day tour (we used to do two tours per year, but we are suffering from the Aging of the Force). Some are nearby, some require trailering. * Nickel Era Touring Registry, an "Affiliated Registry" of HCCA, accepts 1932-and-earlier vehicles and has one annual 5-6-day tour in widely dispersed areas (Utah, Idaho, Washington, various locations inside California), and definitely requires trailering. Our superb 2023 tour in SW Utah had about 34 cars from 1912 thru 1932.

I'll be there with some smalls in #398

Time to clean up the Buick, too, now that the barn dust has blown off.

And the motto of the Armor branch is, HAUL AZZ AND BYPASS!

Isn't the booster--and associated plumbing and adjustments--the only variable in your test procedure?

Looks like the t'stat housing of a 1925 Paige 6-70 (large series), but which did NOT have the adjustable feature from the factory. I have a 6-70 engine from a parts chassis as a backup for my 1922 6-66. Paige is the most common (!!!) of the marques using the Continental 8A/9A/10A engines. My guess is that the adjustable mechanism was an available modification kit. My 1922 Paige 6-66 (nearly identical engine) had a smaller t'stat housing.

Link not working, Karl

It's gratifying to have that power in my old age! 🙂

A trusted friend who runs a boat repair shop servicing boats operating in both fresh- and salt-water environments says magnesium anodes for fresh water (us) and zinc for salt water (that would be @edinmass 🙂 )

I'm sure you do, Bernie.... 🙂

Agree that a top frame must be duplicated from another MoPaR. Need to find out which other MoPaRs used the same top frame, and that will be a narrow window. Then you must network to find a suitable car with top frame that has not yet already been finished--or (another unicorn) a finished car that has detailed tracings from its restoration. Be prepared to pay a VERY large deposit to borrow one for duplication.

As I said in another thread, the Inflation Calculator on the internet dashes all of our hopes of making money on our vehicles, to which I will now add even without factoring in opportunity costs. It may be a function of my advanced age, but I'm only interested in vehicles I can drive now, not projects.

Do we have a Rolls-Royce owner or mechanic to weigh in on the suitability of "modern" antifreezes, especially for our cars with aluminum components? I saw (but don't have) a RROC article from about 10 years ago which strongly urged "No OATs"--OAT meaning Organic Acid Technology. My recollection is that RROC found OAT antifreeze to be worse than unsuitable for pre-war cars. I don't know the science, but do in fact remember the "No OATs" mnemonic.
