its probably going to be a 1999-2000 and I don't want to add nitrous or FI. I though about a forged bottom end w/ aluminum block, intake, aggressive cam, heads, roll bar, DR, tune, high compression pistons, full exhaust, CIA, chip, programmer, gears, and a short throw shifter. I have no idea how much hp that would make, how much that would cost, or if it would even work together. Any ideas sure would help.

 

sounds like you have a rock solid plan. you consider a 5.4L build its about as expensive to build an entirely forged 5.4L (includeing a new cylinder block) as it is to get a forged rotating assembly

 

actually let me refraise that question how much money would it cost for a 4.6L to make 400+hp in Natuarally aspirated form.

 

Umm, you wouldnt get 400 rwhp N/A. Sorry but wont happen unless you bore and stroke it, but then its not a 4.6 anymore.

 

In 2V form? If so, it ain't gonna happen.

 

what do you think would be the maximum I could get out of it.

 

umm about 340

 

how close would a Mach 1 mustang 4.6L DOHC 4v get me towards that number.

 

Much closer than a 2v.
