If nothing else it will be an interesting cam to run. It is one size smaller than the XR292R that bob is running which as bob remembered is 254/260 @ .050.
On 03/03/2006, before we had our own dyno, we ran a 9.7:1 compression 451 stroker with our ported 452 iron heads and used the XR292R solid roller. These are the dyno results:
RPM..............TQ/HP
3900............547/406
4000............546/416
4100............554/432
4200............573/459

Now, the XR286R as a street/strip option for a 440, yeah it ought to be exciting.
