The truck will feature a Clatterpillar 1693TA engine. This is a big engine and took a lot of carefull "adjustments" to get it to sit in the frame and not clash with the dog house. With the big engine (Probably the biggest horsepower engine (425HP) available in a pacemaker in 1970) I needed a larger air breather unit and bigger exhaust stacks. It will also need a bigger radiator. You will note from the photo's that the exhausts are not fitted to the cab rear. Instead they are fitted to the "Eiffel tower" frame. This looks quite pleasing and in keeping with the rest of the build. This frame did not appear until 1973 (I think) so mine being a 1970 model has had the exhausts removed from the cab and the Eiffel Tower retro fitted at a later date. The frame and the bottom half of the cab will be dark blue, middle of the cab white and the top of the cab light blue.
Thanks for Looking!
