Back at it

Ok well after spending that last like year doing other things boot camp esc. I am back to working on my mustang I have a 3.8 like most everyone here its a 04 and I am looking at doing some serious work to it my goal 450-500HP its going to take a lot of work I know the first thing I am looking at is forged internals and new heads from SuperSixMotorSports as well as a M112 supercharger. Exhaust is already done for my car 2.5 inch pipes from headers back, so that it taken care of, how much do you guys think I should take off the heads to get myself a lot of power. What else do you guys think I should do to the car I want to put lambo doors on it eventually so is there someone you can recommend that is good for kits for the mustang. I have about a 5000$ budget for my engine and would like to get started in March!

The reason I want to get so much power out of the car is that I want it to beat me Old Mans 4.6 on the 1/4 mile so I really just want to get it down to mid 10's to low 11's and I would be happy I am used to working on the 4.6 so I kind of know some of the numbers it will take him to get down the 1/4 mile in 11's right now he's at 12.6 at a mile high 11.8 if converted to sea level, when it comes down to it I want to beat him thats it. I don't really know the numbers that will be required though.

This is not a show car I do want it to look nice but this is going to be a 'toy' car for lack of a better word. After I get back from my next deployment I plan on purchasing a 1967 fast back and I will work that up to be my 'show car'

I don't know why but I kind of like the Lambo doors this is still and option for me I am not dead set on putting them on.
