PI HEADS AND COMPRESSION RATIOS...

delgadog · December 19th, 2006, 03:57 PM

hows everyone doin? i'm new to the site but not to mustangs. i used to own a 2000 GT and i loved her so much. i added a 70mm tb and a cai, it gave it a lil pep, i wasn't complaining. now fast foward and i am carless. i'm looking for a 96-98 gt and i'm wondering, if i do the pi head swap or just port and polish them, i know i can get better flow and up my compression. but how can i add pi heads or port and polish but also keep the compression low around 9:1? is this even possible? thanks.

All you would need is different pistons. Then you can safely come back down from 10.5:1
