What hardware do I need for PI swap?

Contact Randy S in the Ford Parts Forum area on Modular Depot. Tell him what you are doing and what you have and he will know exactly what you need. He has good prices also.
You can find the intakes used for @120. Look in the classifieds here and on Corral.net
 
Don't forget the timing cover gaskets (there are three seperate ones) and also if you have never replaced the exhaust gasket between the manifold and the midpipe on the passenger side then you may want to get a new one of those as well. Get a new thermostat while everything is apart, just to be safe, and the thermostat gasket as well.
