Here's the monster of all Norton cams - the Sifton 480. So much lift that it requires extensions on the lifters (see spacers brazed onto the lifter blocks.
The comparison - JS0 is equivalent to stock Norton, JS2 is equivalent to the PW3, JS4 is equivalent to the sifton 480
This cam is going into a full race 920cc on alky. Hot as it is - its still not any hotter than the HD XR 750 dirt track cam.
