Doug Maney Posted May 4, 2010 Share Posted May 4, 2010 The intake was raised to get fresh, clean air. I don't know if it had to be ordered specially or if certain models just came that way, like P (straight truck) chassis that may be used for dump or mixer work. They would be used off road more than most and need to get the dust free air. If a tractor was going to be used as a vocational truck the higher intake may have been possible to special order. Maybe someone knows for sure, lets wait and see. Quote Interested in Old Trucks?

Freightrain Posted May 4, 2010 Share Posted May 4, 2010 My truck has the "P" motor(non turbo, but split intake manifold) but had the short cap on it. I also liked the tall pipe and ordered the chrome extension for it. When I bought the truck, the cap had a large dent in the side where the wing window had hit it over the years when opening the door. Quote Larry 1959 B61 Liv'n Large......................

JerryB Posted May 4, 2010 Share Posted May 4, 2010 I never knew exactly why they came out with some longer but the longer one got rid of a lot of intake noise in the cab so I liked it better.
