purple cam specs

I am looking for the specs on an OLD cam I have-my dad grabbed it in the 70s so I dont know much about it

it is a 340 manual purple shaft-thats the story anyways
the guy pulled it out cause it was too much for his auto-prob stock converter

is this prob the correct one?from mopar performance
1 P4120655 Camshaft, 0.557"/0.557" Lift, 296/296 Adv. Duration

if so what are the rest of the specs-center angles,overlap ect

I have dyno2000 and am looking at different builds
its going into a 360 that has been worked-the 340 cam in it now is too small :)
its gonna come apart and measured up-needs more compression
doing this on no budget-using what we have
