6.0 in 99 mustang
The AJE kmember/dynatech headers is an easy swap that almost puts itself together!
I didn't personally use the factory pump so I cant comment on what it is good for
The hardest part for me was the wiring/getting rid of all of the unneeded garbage when doing the swap.
Look around on here and use the search becuase there are a few 99+ cars that have been done
