Help setting up Coffman Hurricane

[tor*p*do]

Got a used 750 motor and this Coffman pipe
Pam Coffman said it is an original Hurricane, no help on specs
anyone run these or know where to start on jetting?
Thanks!:bigok:

Ended up at 85 Lo, 165 Hi
and 1.25 turns Lo, 1.5 turns Hi
A little rich, dark but not fouled plugs, good piston wash
Hits hard! Love this pipe!!!
