Newman Cams

[Stuart Giles]

If the maximum lift figure is 'off' when you install any new cam, it's almost certainly going to be because the keyway isn't accurately placed in your timing gears. The cam grinder references all the lobes from the camshaft keyway. Although I've had to make an offset key for a number of motors to get the timing right when testing the usual number one inlet, all the other lobes have been spot on once the right key is in place.

@Charles P did you turn up a steel hub for the timing wheel to create the adjustable gear using a re-machined factory outer?
