Default Long stroke, short stroke. More than you want to know

Long stroke was good for getting the car through the muddy roads in the old days. It is also good for tractors and trucks that pull heavy loads up hills or pulling a plow.

Short stroke is good for a higher RPM range. Other words the engine is more flexible for using in a car now days.

Most of you are to young to remember this, in 1955 when Chev came out with there short stroke 265 it 3=3/4 bore and 3 inch stroke. We could not believe how fast they were. They would 6000 rpms from the factory. I would not try that with a stroked Model A .

Yes I have turned a stock stroke Model A to 5000 rpms at a hill climb, but it had my home built over head on it. I was not worried about it lasting a long time. Funny thing it broke valve lifter and I still had the fasts time of the day.
