Our GE series of cams use the same nut and bolt
that came on the later 911’s. If you are upgrading
your cams on a pre ‘78 911 you will need different
cam housings and hardware. Two per car.

911 camshafts are an advanced cam capable of high
performance and smooth operation. His cams are made on new
billets, not a welded regrind. They are a large journal, bolt style
cam with a drive on the left cam for mechanical fuel injection,
and a drive on the right for a power steering pump. The large
journal billet is an advantage in keeping the cam straight and the
base circles large.
