Ive been considering the idea of putting a high compression 5.4 into my stang out of a f150. I know I can get the adaptor plates from riechard racing and the motor mounts are the same. Im going to use pi heads and intake. Is their anything special I need like the egr connection cause the deck height is higher and the intake will sit an inch higher than on the 4.6. Also what exhaust will I need since the heads will also be in a little higher position, anyone, thanks.
