[SEL] OT tractor engine question....

[R and E Freeman]

All the Ford Falcons here from 1962 till 1976 run 6 cylinder engines with
the inlet manifold cast with the head. A very successful engine they were
too.They run from 144 cubic inch to 250

Bill,
Would be curious to see a picture of what you are talking about as I 
can't recall seeing anything like what you are describing. But my guess 
is that it has nothing at all to do with efficiency or heating speed, 
but more to do with reducing manufacturing costs. Even with fixturing, 
it takes time and mill work to machine the head and mating intake 
manifold flat from the raw castings. If you are able to eliminate this 
cost you can go to market with a lower cost product and gain more sales 
that a comparably sized tractor. But this is just a guess......
