Indeed, checking nad27:

# 3200: north carolina ---: nad27
<3200> proj=lcc  a=6378206.4 es=.006768657997291094
lon_0=-79 lat_1=36d10 lat_2=34d20 lat_0=33d45
x_0=609601.2192024384 y_0=0
no_defs <>

and for nad83:

# 3200: north carolina ---: nad83
<3200> proj=lcc  a=6378137 es=.0066943800229
lon_0=-79 lat_1=36d10 lat_2=34d20 lat_0=33d45
x_0=609601.22 y_0=0
no_defs <>
