A master fabricator, Larry designed this special lock washer...
That particular engine was under the hood at Larry's greatest accomplishment, winning the 2007 All Star Sprint Speedweek title with Shane Stewart (Larry's favorite driver) behind the wheel.
Through the years there have been a number of Top 5s and many Top 10s. In a recent race at Waynesfield(OH) Raceway Park, he finished Second against a tough field. No doubt about it, he had the oldest car and oldest engine!
That power Larry might miss when compared to the high-dollar mills he makes up for with methodical tuning of his powerplants.
He explained, "I carefully tune my engines to be consistent with the particular track.

...to keep Dzus fittings from pulling through the fiberglass panels.
"The fuel system is the most important engine component when considering the trade-off between power and reliability. With a high-speed track like Eldora, you have to adjust the fuel pressure and jetting to sustain a constant wide-open throttle. With a short track, the system must be flexible and be able to deliver power when getting back on the throttle.
"I do a lot of my work at Dick Hickernell Engine Service, but I do most of the assembly at my shop."
"Shop" would be putting it mildly, as Larry has about 3,000 square feet to place a multitude of vintage machine tools that he has accumulated over the years. "The milling machines date back to the 1970s while some of the lathes go back to the 1940s. No CNC or CAD here, I feel very comfortable working with those old machines," he said.
This special aluminum bar...
This special aluminum bar with its four adjustment holes allows longer radius rods to be used.
The building is a former grain elevator which he has converted to a shop where he has accomplished his amazing tinkering all done in the old school way, of course. He does a vast majority of his work by himself. "I like doing it that way."
One of his better ideas was the installation of a service station lift rack which enables him to do setup work underneath his cars while standing up. "And it also enables me to turn the car around so I can push it out with the nose pointed outward," the retired 30-year Dana Corporation employee explained.
His fabrication skills are also very evident on his Sprint Cars. "I fabricate my own bumpers, nerfs, drag links, tie rods, wing trees, and Jacob's ladders."
And if you look closely at the Dzus fittings, you will see a special Wood lock washer installed with them. "Makes the fitting much stronger and prevents it from pulling through the fiberglass panels," he explained.
There is also a unique aluminum vertical bar on the sides of his cars. "It has a number of holes which allow large rear adjustments of radius rod locations. I try to keep the radius rod going uphill toward the front of the car which allows for a longer radius rod and greater forward bite."
Another Larry Wood innovation on his Sprinters is a front sway bar that he designed and built. "It is about 13 inches forward of the front axle. Its purpose is to change the roll center of the car and aids in the driver handling and control."
