Back in the late 40’s and early 50’s, most young men wanted to join the S.C.C.A. and race automobiles. Compared to circle track racing, the appeal of road racing was new and extremely exciting. Most of us bought MGs, which could be had for about $1800, and a helmet for $20, and we were in business. As there were no “production” or “modified” classes, etc., we were grouped only by our displacement so that we all were placed in what would be labeled “modified.”
A little research showed that there was an F.I.A. class for cars 750cc and under Class “H.” The first person I recall exploring this was a New England genius named Candy Poole, who built (or at least entered and drove) a Crosley powered machine called the “PBX,” which was much smaller and lighter than cars most people had ever seen. It opened a lot of eyes at Watkins Glen and other eastern races, and it ran for years and nearly always won.
The Class “H” specifications were practically wide open: displacement limited to 750cc, and to make it a sports car it had to seat two people (try that in a modern Sports 2000!), have head and tail lights, a starter, spare tire, at least one door, a handbrake, reverse gear, and for some larger races it had to swallow an F.I.A. suitcase (about the size of an overnight bag.) This left plenty of room for imagination!
I had sold my MG, so I set about building an “H” car with the help of ex-Californian John Wood. My goals were simple: it should cost no more than a used MG, and it should beat them!
I used a chrome-moly 2 ½” tube ladder frame, Planer suspension in front, using lightened Studebaker parts, an MG T.C. gear box, Henry “J” rear axle, cycle fenders, and 12” mag wheels from Midgets ($10 a piece drilled to my bolt pattern from Pop Dreyer in Indianapolis, where I was then living). Joe Silnes, race car builder also from Indianapolis, made me a simple aluminum body all held on with “Dzus” fasteners so that the car could be stripped down to the chassis in five minutes. The engine received the state of the art treatment: Navy steel crank, balancing, Braje intake manifold, two SU carbs, oil cooler, Mallory ignition, chromemoly straps under the main bearing caps, large oil sump, slightly stiffer valve springs, and different cams starting with Iskenderian, then Harman, and Collins, and ending with Weber. The engine started with 27.5 horsepower and gradually crept up to 55.
I believe Paul Gongelman was high point man in the S.C.C.A. in 1953 racing a light Nardi with a BMW Flat twin giving big bags of torque. Bruce Townsend had built a very pretty little red Crosley special looking for all the world like a shrunken “D” Jaguar – except the latter would not appear for a couple of years. Bruce won Class “H” at Road America for four years running, being clocked at 110 m.p.h.
About this time Roy Kramer, editor of “Piston Patter” – the Chicago region S.C.C.A. magazine – threw a little quiz question in one issue: “What American made, mass produced, 4 cylinder, water cooled engine would fit right into Class “H” and put out over 40 dependable horsepower, yet can be carried around on one arm? (or words to that effect). After several days of intense head scratching, I came to the conclusion that it could only be a Mercury Outboard. By this time the Crosleys were getting a bit long in the tooth; nothing remains static forever in racing. The OSCA, which eventually killed the era when just anyone could build a low cost winner, had appeared but was priced about $7500.00 (a good bit higher than the cost of a new Cadillac and only about $2500.00 less than a Ferrari) so they did not crowd all the specials off the track at once.
Inspired by the quiz question, I had a very nice visit with Carl Keikhaefer of the Mercury Company, and he agreed to install an outboard engine in my car for Sebring – for free yet – plus he offered to have his team of professional race car mechanics rebuild the car completely, and then lent full factory support for the race. I ended up with a car which was not only the first, I believe, to use a Mercury engine but also turned out to have the smallest displacement (621cc) ever entered in Sebring before or since. I selected Paul Gougleman, whom I had known since school, to co-drive with me. It was a real thrill to be competing in the same race with Fangio, Moss, Taruffi, Dreyfus and a dozen or so other drivers whose names were household words to sports car fans. I believe we were leading the race on Index of Performance when about halfway through our greatly over stressed Fiat “Topolino” gear box gave out.
An amusing side light of the race happened when Paul was out on the 5 mile track: the carb needed an adjustment so he stopped, flipped off the hood, fixed it, and tore on. However, he did not fix the hood quite right, and while getting up to speed it flew off. He stopped again and put in on right, but not before a 300SL ran over it. When he returned to the pit with this big Englebert tire track running right over the front of the car, we all nearly fainted!
I raced the Bandini another year with good results, but it was getting fatigue cracks in the fatigue cracks. Paul had a Giaur with a 70 h.p. Moretti twin cam for sale so cheap I couldn’t refuse. It always set fastest lap time the first lap but was boiling at the end of the lap. All the “experts” could not fix it, but I felt they must be overlooking some simple things – and they were. We solved the problem and won more than a few trophies that summer.
However, when I had sold the Bandini, I had kept the Mercury engine, never being sure if Mr. Keikhaefer would want it back someday. For about ten nights after work, I labored mightily to stuff it into the Giaur; I had to make an adapter plate for the Fiat 1100 tranny and clutch, redesign various controls and radiator plumbing, but we made it to the race. To my surprise, we turned faster laps than the Moretti had done on the same course that spring. I took it down to Nassau for their first race, and got a second.
Keikhaefer had now put a slightly better Mercury engine into the Stanguellini car which Briggs Cunningham had imported to win its class at Watkins Glen, which it of course did with ease. With the Mercury engine, it set some international records at Daytona Beach. About this time Herm Behm, a friend of Keikhaefer, had become the Stanguellini importer, and had a factory entry for the 1957 Sebring to drive with Carl Haas. By this time the race was so important that only factory entries were accepted. Due to poor health, Herm found he could not drive, and invited me to take his place. Carl and I won our class which was quite a thrill that every driver does not get to enjoy. After Herm died, I bought his car with the Mercury engine from his widow, and continued to race it with success. (One year I drove in 10 major races at a total cost of $811.00 including tires, entries, parts, hotels, etc. Since I probably was the tightest Scot in racing, this was most likely a record, but it does go to show one reason why Class H was so popular.)
By this time I had become the Stanguellini importer, and was very busy with Formula Juniors, “demonstrating,” racing, and selling cars and parts. However, I wrote to Vitorio Stanguellini in 1958 and told him that if he would enter a sports car at Sebring, I would sell it for him. I let the word out that I had a good entry, and was looking for a co-driver. All he had to do was meet my specs and buy the car for cost (which was not an unknown practice at the time). I sold the car to a good driver, Bob Roloson, and we went down in ’59 to find our competition was two factory made OSCAs and two factory made French D.B.s.
In the race we were ahead and faster than one D.B., passed one OSCA and were steadily gaining on the other. I felt sure that we would end up 2nd in class, but a light rain came like you only see in the tropics and Bob lost it at speed and hit a bridge support, pretty much destroying the car. Seemingly impossible, he was unhurt.
Candy Poole, the father of the class and one of the very best, John Mays, “the Wizard” who, to my knowledge, was never beaten if he finished, and Martin Tanner, who built six cars with aluminum tube frames which are all still in existence, and who made Saabs look and sound like Offenhausers.
(Editor’s Note [Joe Puckett]: In the interest of H-Mod history, I would suggest the great Harry Eyerly, Don Miller and Red Le Grand be added. Harry because he too never lost! Don Miller and Red Le Grand because they produced many contending cars between them [over 50 in number] and quite a few of these were champions!)
