Re: [FWDLK] 56 Fury linkage vs 57 Fury Linkage

In such a situation, you would effectively have a 4 cylinder engine.
Unfortunately, the firing order does not alternate between front and rear
halves of the engine. At one point in the firing order, rear cylinders 6, 5,
7 fire in sequence. This 4 cyl would be VERY rough running!

I met a fellow one time that made an air compressor out of a V8 engine. With
a dual plane intake manifold, one side fed fuel to 4 cylinders and the other
was wide open for just air. It ran smooth on 4 cylinders and pumped air with
the other 4. The pumping 4 cylinders had the exhaust valves left closed all
the time and air was compressed on the "compression stroke" out the spark
plug holes.

Is this such a bad thing, for the engine, to have gas be delivered,
initially, only to the rear
cylinders?  The front cylinders are still getting the oil supplied to them.

The new Hardly Dangerous  motor cycles have a provision where, at
prolonged stoppages,
the rear cylinder has its fuel supply interrupted, in order to avoid any
overheating of the engine.

And, we all know about the current V/8-6-4 provisions on modern cars.

So, outside of a racing venue (yeah, like any of us do that, anymore),
what difference/effect would
there be, using the 56 aluminum intake,  with a progressive linkage
employed, with 57+ m.y. carbs,
wherein the front carb begins to supply gas when the rear carb's
primaries open to about 30%?

BTW, I've got an old (what other kinds are there?) issue of Hot Rod,
where it shows you how to
adjust your 57+ linages so that all 8 barrels operate in the manner of
the 55-56 versions.
