Can anyone give me information on the following camshaft numbers (model year and engine used in) and the "Intake Overlap TC with 0.1 mm Valve Clearance" values for this cam? The cams have an 'S' stamped on the end. I'm considering using them in my rebuild. Any comments appreciated.

Left cam: 901.105.109.01
Right cam: 901.105.110.01

Thanks,
Rick

According to the parts catalog, those were used on late 1965 911 engines.

Do you have access to the 'Intake Overlap TC with 0.1 mm Valve Clearance specification' for these cams? I only have the '72-'73 tech spec booklet.

Thanks,
Rick

 

As I revisited this cam, it looks like it was used not in late 1965 but for most of the MY1965 production in engine type 901/01. Factory manual says the intake valve lift at TDC with valve clearance .1mm is 4.2-4.6mm (.165"-.181.") with 4.3mm (.169") optimal.
