You might consider the Voodoo 702
http://www.lunatipower.com/Product.aspx?id=1775&gid=287
The Crower 60916 with 278/289 advertised compared to the Voodoo 702 with 262/268 advertised duration. Both have similar .050" duration (within 2 degrees on the intake) and both ground with a 112 lobe separation. The voodoo cam has 132/140 degrees ar .200" but I'll suggest you will not get that information from Crower for that important evaluation, like comparing the duration between .050" tappet lift and .200" tappet lift.
I didn't note the compression involved here. But note the Voodoo lobe has shorter seat timing and the all important additional valve lift over the Crower lobe, keeping this in mind where the cylinder heads will flow to.
