Well adding up the costs of the 466 project it will be in the $4000 dollar arange and i dont feel like tearing apart my car just yet so project 466 will be delayed into the future when i get my job as an engineer making the big bucks. Im sticking with the 5.0, for now, im springing ofr a kenne belle blowzilla supercharger instead. how much boost can i run safely on a modded engine? And will the supercharger work with my B303 cam. Im gonna take the engine out in spring and redo the heads with roller rockers and more porting and polishing. compression as far as i know is stock. i have a gt40 lower intake to go with the supercharger.
