Running Bird, T-Rex's 960cc 741 Scout Racer
|
This is the latest Rex Hosking Racer. Rex known affectionately as T-Rex for
his love of Dinosaurs as well as Indians, has built and raced several racers for
several decades. This is his latest, aptly named 'Running Bird".
It has sports scout barrels and sports scout heads, 13/4 " Chevrolet valves,
Bonneville cams and followers and lightened, polished and fastidiously balanced
chief flywheels in 741 cases making a capacity of just over 960 cubic inches!.
Everything carefully lightened and tweaked for less weight, just take a look at
the oil pump that Rex has shaved 3lb's of weight off!
It has sports scout rods, again polished to fling that horsepower robbing oil
off more quickly. In these photos it is utilizing a 841 front drum, this
has since been changed to chief drum provided by me. It inhales
through a Linkert 344 (Chief) carb that has had the idle hole closed off and
installed out with Bonneville nozzle and venturi. It is 12volt equipped
and the coil is mounted out of sight on the lower cross tube between the takes.

The front and rear frame sections are standard 741 though modified from stock
with extra mounts, such as the front (close-up here)
and middle head stays etc (close-up here). Have a look
at the other photos and you will see more of Rex's self designed and built mods
more closely. The gearbox is stock 741, and the oil pump has been lightened by
some 3lbs (see this photo), wheels are 18" with Dunlop
MR277 325 dual profile and Metzler slicks.
Rear sprocket is a std 36 tooth, and he has a selection of 18-20 tooth sprockets
for the front. These photos (click the thumbnails for a larger view) are showing
headlights, kicker arm and license plate in order to get some running in
miles on the street prior to burning up the track. These have since been removed
and is now adorning it's race numbers and Rex has raced it a half dozen
times without a hitch.. Rex just missed what would have been its first
meet the Pukekohe races in Feb 2001.
