Simon,
I think Competition Cams had a write up on re-curving a distributor in
their tech tips, once upon a time. I did it the hard way, on the road
with timing tests, once, and it was a pain but I can't remember the
procedure. The absolute best way is to find some old fashioned shop
with a distributor machine and give them your cam card. They will
curve the distributor to match what the cam should need.
Cheers,
Chris
