On 7-7-20 i spoke with the tech rep at Clay Smith Cams regarding the 264 profile.
The original 264 camshaft was advertised @ 214" @ .050. It was closer to 215-216 degrees.
That was the reason for the lumpy idle even at a 112 L/C.
That profile will still be available but will be advanced 3-4 degrees.
A new 264 profile was just made a few days ago & will have 211 degrees @ .050", but the initial rate of lift will be increased. Lift will remain the same.
The result will be a smoother idle for the 264 camshaft at all lobe centers.
This camshaft will be ground with 3-4 degrees advanced.
Possible in the near future there will be a 264 cam with 206 degrees @ .050" with even a smoother idle.
There will be a slight power loss with these newer profiles.
Recommended valve spring pressure should be at least 100# seat pressure.
When you order a 264 cam in the future you will have to mention what profile you want. Bill
