I wont be 2v. I'm going 4v. So looks like I'l have to have custom pistons made to acheive what I'm looking to do.. Just fantastic.

Also [MENTION=92839]MyFX4Project[/MENTION] Your 4v setup will be around 10.3:1
SO no custom work for me I can use straight flat tops with valve reliefs with E85 and Boost.

My friend today said he thinks my truck will hang with his 2012 ecoboost when im done. I doubt it but we're definitely gonna find out. Also found someone to tune it when all is said and done. Gotta call machine shop tomorrow for head estimates.
