How are Datsun cams named? I am familiar with the duration, eg 246 degree etc.. What does a 72 degree name mean?

G'day Nat, If you are interested, I have a Crow Cam that you might be able to use. It came out of Martin Harris' (ex OzDat Lister) 1600 Rally Car. The Cam had very little use - (1.5 Rallies) before the motor blew. You could go a lumpier cam at the expense of bottom end torque. Here are the specs.

Morning listers !!
I am having trouble finding a cam that is suitable for
my new motor, I have beening looking supplers up on
the net, but they don't exeactly give me faith that
their product will work.
I rang up one company and all he asked what motor
was it for (L18B) and what I was going to use it
for(rally car) and thats it. Then he just said
everyone uses this cam, I asked why and he just
repeated that if it a rally car this is the cam I
need, He needs more info then just that!! Does anyone
know of a goood supplier of cams for rally motors!?
Cheers NAT
