So, if I wanted to build a Bad Ass N/A motor. But I wanted to use the 4.6. What would you do. I'm thinking a 13:1 compression. 4v ported aluminum heads, aluminum block with an aftermarket intake and some custom cams. Rev it to 7500 and call it a day. Any one got a guestimate what kind of power that would make. Ported 4V heads are supposed to max around 600hp before needing FI. Anyone know some real life numbers?
