The archives seem to suggest that 3.8 and 4.2 camshafts are the same between series 1 e-types. What about between Mk10 and e-type in the pre-'68 era? Can’t seem to find anything on that, but I suspect the cam profiles for the straight port heads were the same in the saloons as in the e-types.

Camshaft differences?

Cam lobe dimension, another try to find XK

are your lobes showing? is there a cam cover off or a cam on the shelf…I want to verify the cam lobe…heel to lobe tip, dimensions on the cams…both Intake and Exhaust, and and both lifts…so…for C2444, C2237, C5717, C5718, and if you have a Mark7…C4488, C4489, C4038. SO far…on used cams…look for approx 1.424 on C5717, C5718: and 1.360 on C2444, C2237. 1.349 on few lobes on the cams in Maddy’s FHC…unknown cam…can’t find C number yet…but it is a later replacement cam with the MC casting numbers……
