PI modulars

[Venomized]

What year did this start? I am thinking of doing the PI swap on my f150 to get a little more umph but have no idea what year they started this.

Also I have read some threads that the 98 had the romeo motor (whatever that is, remember Im a pushrod guy) so enlighten me please

pi motors started in 1999 for mustangs, i believe 2003 for everything else

for mustangs it was '99. crown vics and alike '01.

for trucks the 5.4 got PI in '99, the 4.6 got PI in '01

Ok cool. I think Im going to look into it once winters over and I have the stang to drive while the truck sits.

only thing different from the romeo and windsor heads is the number of bolts for the valvecovers. they were made in different plants because there was a fire in one plant. so all heads started to come out from the other plant. after everything was up and running again, the heads were back to normal. so a 96 mustang can put 03 valve covers on the heads if you would like.

you will also need a pi intake also because the ports are different.
