Suggestion, call Tim Goolsby ( ext. 102) at Bullet Racing Cams and see if they have any cam cores on hand. He can custom grind a Harold Brookshire designed UltraDyne lobe.
It won't be quite as aggressive as Harold's Voodoo lobes. But with similar .050" duration if desired.
Tim can match the exhaust lobe and the desired LSA to your needs.
Example UltraDyne lobe H31
280 at .006
232 at .050
.3334 lobe lift
0.500" lift w/1.5
Or something similar
