I am wondering if anybody on here has any idea where i can find specs on a 2004 5.7GI-E. I am looking to do a few performance upgrades and I can not find specs. I already have a computer nailed down, I need engine info so I can spec out a cam. The details that I am looking for are as follows. Cylinder head type, valve port and diameter, compression ratios, head gasket volume, current cam and lifter specsand fuel system info. I have searched Offshore only as well as various other forums and sites. I have all of the stock part numbers from the Volvo Penta Store. Any help would be appreciated. My goal is to achieve around 400hp which i know is very possible. I am contemplating aluminum heads also.

Thank you

 

the factory manual will have all that
