The Mightiest of the Mighty! Bill Miller’s 12 Cylinder Packard Sports Custom: Part 1

Hi Gang…

Not many cars are going to be able to beat the size of the engine used by Jerry Gardner and his Voodoo Special from ’52 (click here to review the story on Jerry’s car), but Bill Miller’s custom metal bodied special beats it – and then some too!

And like Jerry Gardner’s sports car, Bill Miller’s sport custom is “special” in every way.  It’s based on a 7 passenger Packard limousine and had to be shortened by nearly 40 inches to get it to its 105 inch wheelbase configuration.  It retained its original 60 in tread which makes it the widest tread I’ve seen on a special to date – and the only 12 cylinder one I’ve found too (metal or fiberglass).

And who built the custom built metal body?  By Bohman of Pasadena, California – the legacy company of the famed coachbuilder, Bohman and Schwartz.  How much more “special” can a “special” actually get?

Let’s see what it takes to build a car at this level:  The Bill Miller Packard Sports Custom from 1956.

Bill Miller’s Special
Inches, Inches, Everwhere
Road & Track, March 1956

The road to building a “backyard” special can often be a long and bumpy one, and, like as not, a good many shining ideas about what the car could and should be must be dropped along the wayside.

Usually the concept of a sports car includes the qualities of lightness and agility.  In the case of the special shown on this page, however, builder Bill Miller of Los Angeles was not primarily interested in competition; he wanted a solid, handsome “boulevard” sports car, distinctive in styling and with tremendous acceleration over a wide speed range.

His main source of components – a 1938 7 passenger Packard limousine – would not have seemed overly promising to many an enthusiast, but when you set out to build your own car on any kind of budget, you commence with what you have.

The chassis was shortened by 39 inches to 105 inches, but the original tread, about 60 inches, was retained.  Modifications to the enormous 476 cubic inch V-12 engine, which originally was rated at 175 bhp, included a .010 inch over-bore and a special manifold incorporating three Stromberg carburetors. 

Although Mr. Miller has not tested the engine on a dynamometer, output should be considerably improved.  To garb the massive chassis and engine, Bohman & Sons of Pasadena, formed an all-steel body using a suggestion of Packard Clipper around the headlights and a bit of the original limousine at the back portion of the rear fenders.

Bumpers are ’36 Cadillac V-16, with a gentle scoop taken out in front to conform to the grille oval.  Behind the grille is fitted a specially constructed radiator to cope with the cooling problem of a large engine in a small space.

Since this was to be a fair-weather sports car, no attempt at weather protection was made, but extra care was lavished on a spacious, beautiful interior, with an orderly bank of Stewart Warner instruments.

On year and $6500 were expended on the 4000 lb special (windshield still to come), but already Mr. Miller is looking for greener fields.


What an impressive car and rumor is that it’s still with us – last seen about 10 years ago in Los Angeles, California.  What fun it would be to see this car again 🙂

So now we have it – the two most powerful specials of the 50’s:

  • Jerry Gardner’s Voodoo fiberglass bodied Special powered by a ’42 Cadillac V-8 346 cubic inch flathead engine
  • Bill Miller’s custom built metal bodied Special powered by a ’38 Packard V-12 476 cubic inch engine

Both were expertly built and represent the most powerful cars of their class (fiberglass and metal body) – until we find the next bigger one from this era!  Happy Hunting here at Forgotten Fiberglass!

Hope you enjoyed the story, and until next time…

Glass on gang…

The Mightiest of the Mighty! Bill Miller’s 12 Cylinder Packard Sports Custom: Part 1 — 3 Comments

  1. When looking at this car it reminded me of another one that was a feature car in the October 1952 Popular Science. It is metal like many custom sports specials of the 1950s. This car was the first Jabro and the start of the Jabro fiberglass body company that built H-mod sized bodies for over 20 years. Many of the Jabros were Crolsley powered and others had 3 cylinder Saab engine. A good number are still vintage raced. More later.

  2. Thanks Geoffrey for this great posting… Super great glass car and love the engine.. My 30′ Packard has the straight 8 and that us a big one… Would love to see what the 12 would be like… Keep up the great work… john sbiegay

  3. ~ i seldom read a Forgotten Fiberglass article that i don’t learn an obscure tid-bit of trivia. for instance when i googled Bohman and Schwartz to refresh my memory of the many beautiful coach-built cars for which they were responsible i discovered that Maurice Schwartz who had come to America in 1910 worked at a southern California body shop before he and Christopher Bohman began their own coach building shop. in 1918 Schwartz was employed by Earl Auto Works and his boss was Harley Earl, later to be the father of “factory styling” at General Motors’ Art & Colour section. Mark Theobald wrote on, ‘Schwartz tolerated nothing but the best in anything that he did. He wasted no time on idle talk and put in an exact day’s work. Yet he was also a warm and kind person who loved and told splendid jokes.’
    it seems apparent that by his choice of V-12 Packard running gear and the firm of Bohman & Sons as his coach builder he expected his “boulevard” sports car to be the finest he could possibly accomplish. i hope it comes out out of hiding very soon.
