I believe the 3 bolt pulley started in 15.

They "copy and paste" quite often. They have the exact same info on the 4 bolt pump in the catalog. Same thing with the different 5.2 blocks.Yeah I wonder if that’s a typo since the 2020 GT500 pumps are 3 bolt.
Based on the information in this thread, you could probably use a jaw puller to remove the flange off your old water pump and press it onto the new one at the correct depth, provided the shaft OD and flange ID was the same between the two.Ford's web site says it comes with 4 bolts for the pulley. When did they change to a 3-bolt pulley for this?
I was hoping to reuse my 4-bolt lightweight pulley.
