PI Heads

What are PI heads?? or PI intake?? can anyone give me a lil info on this, and around how much are they running for??

PI heads are the cylinder heads that ford switched to for the 99-04 mustang GTs. they are also found on F150s and 01+ panther chassis cars. they have a square inlet port with larger valves and a smaller combustion chamber. the PI intake is the intake made to match the airflow characteristics of the PI heads. i got my heads used for $170 on Ebay, but you can buy them new for about $400 a piece from various places. the intake is about $200. on a 96-98 GT there is a 50-70 hp increase from switching to the PI heads and intake. however the compression ratio is increased to about 10.5:1 so using a blower is almost out of hte question. the camshafts used in the PI heads are also different.

So what do i have to buy in order to have a good setup?? the PI Heads, the PI intake, do i also have to change the camshaft??

when you order the PI heads you get the PI cams with them. all you need to install them are a complete set of tools, the heads, intake, gaskets and new headbolts.
