The most important are the camshaft, the camshaft rocker lever roller and the tappet.
Stroboscopically flashed light, triggered by the camshaft angular position, was employed.
Data were obtained with camshaft angle or with time as the independent variable.
Each cam was positioned on a common camshaft, extending the length of the wall, with a successive phase difference of 90".
The phase of the wave at each orifice in relation to the camshaft rotation was determined by temporarily a%xing fragments of mirrored glass to the wall beside each orifice.
This engine was revolutionary in its lightness, with the bare weight of 180 pounds, combined with the maintenance-free valve adjustment using shims under overhead camshaft.
This allows for the replacement of the shims without the need to remove the camshaft.
The shop installed exhaust headers, eight-quart oil pans, oil coolers, hi-rise intake manifolds, racing camshafts with solid lifters and stronger springs, and larger carburetors.
