Since the early 1930s, Jim Harrell was always experimenting with various types of racing equipment. During those years and into the 1940s, he was developing his own products when he couldn’t find available equipment that satisfied him.
By the mid-1940s, Jim Harrell had refined the design for the intake manifolds he had been working on and had the patterns made for both dual and triple manifolds. Around 1945-’46 Jim contacted Dick Pickerel’s older brother and a friend to do the preliminary machine work on his first intake manifolds. On the first several manifolds, Jim used the name TORNADO on the name plates. We’re not sure why he chose that name. Perhaps he just liked the sound of it, or as Dick Pickerel remembers, it was a name that had been around for awhile and sounded like a good name for speed equipment. In any case, Jim had side plates made for his manifolds carrying the name TORNADO. Well, apparently Lee Chapel and his Tornado Engineering Company had already thought the name was very suitable for racing equipment and was still using it. Somehow, Jim got word that Chapel owned the name and was using it on equipment including his dual manifolds—Chapel made and marketed “Low Riser” and “High Riser” manifolds through his speed shop in Oakland, California. Certainly Jim was aware of Lee Chapel's manifolds, but apparently didn’t care for them. However the name TORNADO must have lodged somewhere in the back of Jim’s mind. As soon as Jim was made aware of the problem over ownership of the name, he had new name plates made for the sides of his manifolds. From then on, Jim’s manifolds have carried the HARRELL name.
Apparently Jim had only made a few TORNADO name plates and they were removed right away. However, at least one set of original side plates was still around in the 1990s when Dick Pickerel owned the patterns and made a run of manifolds. The picture below shows dual HARRELL manifolds that had just been cast and machined. Dick placed an old TORNADO side-plate he had on one of the manifolds (with carbs.) to make the connection with the first couple of manifolds Jim made back in the mid-1940s.

During this same period of time, Jim was developing his own racing heads for flathead Ford and Merc. V-8s. Jim's heads reflect his constant striving for performance and appearance. They carry the name HARRELL LOS ANGELES.

The earliest photo we have of Jim (in the hat) and his equipment at the races is from 1946. He is pictured here with Tony Capanna at El Mirage Dry Lake.
The photo is from Veda Orr's book Hot Rod Pictorial, p. 29.
The photo below shows Jim Harrell’s equipment as featured at the 1950 Hot Rod Show in Los Angeles.

Also in the early 1950s, street rodders and custom roadster builders began to take notice of Jim Harrell’s racing equipment. For example, Hop Up magazine featured a beautiful roadster owned by Tony La Mesa in its April 1952 issue. A lot of thought went into this beauty built by Ray De Fillip and into the beast under the hood as evidenced by the presence of Jim’s Harrell Los Angeles heads. The engine was described later by Tony Thacker in these words: “… powered by a bored & stroked 286 Ford with Harrell heads, an Edelbrock manifold with twin Stromberg 97s, & a Winfield SU-1 full-race cam.”

The following photo shows Harrell racing equipment produced in the 1990s from the original 1945 patterns. The equipment shown here is on Augie Esposito's street roadster.

Two additional fine examples of Old School Hot Rodders using Jim's equipment can be illustrated by looking at two high profile roadsters that were recently built or rebuilt.
The first example is the reconstruction of the Berardini Brothers' 404 Jr. record-breaking roadster. During the restoration of the 404 Jr., every effort was made to reflect its former grandeur. The work began in early 2004, when Roger and Sissy Morrison rescued the former race car from obscurity. They turned the car over to Dave Crouse in Colorado with instructions to return the 404 Jr. to a state worthy of its early history. Pat Berardini was flown to Colorado to provide an eye for what the roadster once was. Pat’s goal was in line with the wishes of the Morrisons and Crouse when he insisted that the replacement V-8 Ford engine sit under Harrell Los Angeles heads. Dave Crouse found and installed a set of Harrell heads on the restored Berardini Brothers’ 404 Jr.

The other outstanding example of using Harrell Los Angeles heads and intake manifold is the purple 1932 roadster built by Jay and Joe Kennedy of Pomona, California for Jim Jard of Texas. The Kennedy brothers were also able to obtain a set of new Harrell heads and intake manifold in 2004 to complete their work of art. The purple ’32 is pictured below with Harrell heads and manifold center stage.

Still today, Old School Hot Rodders enjoy getting their first set of Harrell Los Angeles racing heads as illustrated in the following photo of Jim & Nick Harrell's great grandnephew, Alec R. Harrell Carlson with his new heads in 2008.
Harrell Los Angeles heads and intake manifolds are still being produced today from the original patterns (see lakeheaders.com).
