why does my 305 hesitate

happy new year C-10 peeps
i have a 1972 with a 1984 305 with 3 on the tree. The truck has been super dependable for several years and just recently developed a weird hesitation. When I reach about 40/45 MPH the motor runs rough up to about 55 MPH then clears up. Any thoughts ???
fouled plug ?
vacumn leak ?
I can put the clutch in and it rolls down the road w no noise

also can you hear a throw out bearing going bad ?

Thanks , Brian
