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
 
First welcome aboard.
I spoke with the tech rep on 7-7-20 & h said he redid the master a couple of days before that date.
I would bet you have the old profile.
However since the older profile will produce more power, but the idle will be not as smooth.
If you degree it in the older profile will be ground straight up.
I would have to call the tech rep to see if the old profile will be ground 4 degrees in the future.
The only way you can get what you want is order direct from Clay Smith Cams.
The advertised duration will be 264, but the duration @ .050" will be different. Bill
