John,
I just weighed one of the cast iron heads from a 72 429. With just the
springs, valves, and retainers it was 66 lbs. on a certified scale.

Mike: That's pretty close to the number I got from another guy on the list.
I appreciate you taking the time to weigh it.

Thanks!!

Yo Aaron, et al:

Just to clarify on a minor point of Chris'z post. The (approx) 14:1 ratio
mentioned for air/fuel mixture is *mass* not volume. That is, you need (approx)
14 kilograms of air for every one kilogram of gasoline. Since air is much less
dense than gasoline (i.e., mass/volume), the ratio in volume is more like 200:1.
That is, you need (approx) 200 liters of air for every liter of fuel. When
considering the "pump" characteristics of an engine, you need to consider the
*volume* of the fluid being pumped, and when you think about the 200:1 air/fuel
volume ratio, the significance of intake airflow is more obvious.

Just like back pressure, which in simple terms is the resistance to flow in the
exhaust system, manifold vacuum (i.e., the pressure differential between ambient
atmospheric pressure and the absolute pressure inside the intake manifold)
results from a resistance to flow in the intake tract and it affects the
engine's volumetric efficiency. In general, anything you can do to reduce
intake airflow resistance will increase volumetric efficiency and increase the
engine's power output potential.

Ford has added wires to the rear window to clear fog and frost.

D*dge is adding wires under the wipers so they can be freed when
frozen and not burn up the motor.

Ch*vy is adding the wire elements to the tailgates on all of their
trucks. Keeps your hands warm while you're pushing!

I don't have a manual, but I was refering to the
headlights.

That would be great! Where are these tabs? No owners
manual... I have tried to find a Haynes or Chiltons,
but everyone tells me that they are not out yet!!

Thanks,
Ryan
