964 cams
I am just finishing up a 3.3SS built on an SC 3.0 liter block. I have 10:1 Mahle pistons (100mm bore), Carrera heads and of course, the 964 cams. Even with the slightly bumped compression ratio, there is no interference using these camshafts. You will need to cut off the extension on one of the cams that was used for the camshaft positioning hardware. With the valve adjusted to 0.1mm clearance, I set the cam timing at 1.26mm. Hope this helps.

They will work.But AFAIK you want something more racier then those (964) They were made for old style fuel inject and the air plate can not satnd very much over lap in the cam shaft s
So......You could get away with something much more better ! Also if you are bumping the C/R you will want to move Hp up RPM dial a bit . JMO
