I've had 2 1971 340's and they had the 3 spoke pulley with the federal pump. I've also had a couple 318 1971 cars and they had the solid pulley.

What's strange is that the 70-71 parts book only shows one pulley for the pressed on type threaded shaft pump for all small blocks when in fact there are 2 different styles. The part number is 2951901.
