Why the /6

You can 'work on' a slant six, it has mechanical lifters (The early ones!) and yiou can dial in the engine to sound so sweet when finished. Pulling extra performance from a 'Slanty' is more challenging, but more rewarding at the same time. The one barrel was good in its day but we know today that the cylinders did not receive the same amount of fuel. Today we can build digital Fuel Injection systems that give each cylinder a precisely metered amount of fuel every time. So much better fuel mileage is possible. In 1964 I remember reading the Mechanix Illustrated Article that said, "The difference between the slant six and the 273 V8 is not noticed until third gear. The performance is the same up to that gear.
