proformance

[garrytoao]

i have a 2000 mercury grand marquis with a 4.6 non P.I. heads. can i put the P.I. heads from a 98-02 mustang GT and the PI intake on my merc and get better proformance or would it be cheaper to go with different cams? i changed the 2.73 gears out and put in 3.55 gears; better take off but not a lot of giddyup go. i can get the GT heads and intake for free so if this can work let me know or what would. i trying to make it a sleeperi think this question has stumpied the viewing public,i hope someone has a friend thats a speed tech on fords. the block i have is a romeo same as a mustang for 98-02. any help would be greatful

they'll fit and they'll increase static compression almost a full point. oh and make sure you use that pi manifold or you'll need an adapter.

You'll want to first TELL your wife to get a second job so you can buy the necessary parts.. Stage 2 heads from Patriot Heads---Trick flow PI intake--75MM TB--90MM mas-air---24# injectors---Comp Cams stage 2 cams---Ford shortie headers---4:10 gear in the rear--a lentec 4R70W transmission.And MOST of all you'll need a pro like me to install it for you at a reasonable price.

Pi heads with PI intake will work--40hp increase--compression about 10:1--all accessories will hook up.
