Aqua Allisons – Part 1

The Allison engines were used just about every imaginable way. First, they were used as a single engine, then combined as a pair of them, and even three or four of them-all on a single vehicle. Since their development and release in aircraft in 1930, engine builders following WWII began to pry more power out of them and the rest is history.

Going Hohl School

During the 1950s and ‘60s, building and tuning a performance race engine was a different world from today. It was definitely more of a hands-on situation where the feel, sound and smell of an engine were important tools of early engine builders.

Modified Ford Model Bs

It was known as the Model B engine and was produced for only four years beginning in 1932. Sporting only four cylinders, it was basically an upgrade of the earlier Model A powerplant. The “B” engine sported an impressive 200 cubic inches of displacement. Its compression ratio was a super-low 4.9-1.

Ford’s Famous Flathead V8

It was special in so many ways. First of all, it was the first V8 engine for the Ford line of cars. Nobody could imagine the effects it would have on the racing and hot rod world in the years to come. Even in its stock trim, it was a gutty little powerplant, but it would

Growing a Reputation in the Dirt

For late-model stock car engine builders back in the day, it was a different time and a different place. During the 1960s and up until the late 1970s, there were no professional engine builders where a race-ready motor could be purchased. Just ask Morgan Chandler, an inductee of the National Dirt Late Model (NDLM) Hall
