cam identification

i pulled the cam out of a 305 im biulding and it looks reasonably new, the engine also had new valves, springs, etc and new lifters

im wondering if this is a performance cam or not i measured the lift and it is about .291

there is 2 sets of #'s stamped on the distributer gear end one is 576650 and the other is 1107R

it has D9 stamped in on the cam inbetween the bearing journal and the distrib gear and on the other side of the gear it has1539

then on the other end it has E8 on one side and 11 on the cam inbetween the fuel pump lobe and the first cam lobe

thanks for the help, i have a summit cam to put in anyway so it doesnt realy matter if i found out
