Another opinion question

I understand what your saying about trying to guess prices. Even if you do that for a living it's impossible to know what they charge in another part of the country. Anyways let me put it like this. I want a stroker for the low end tq to make it a good light to light car. However I want to be able to cruise it all day long without worrying about overheating and still have a mid to low 12 sec car on pump gas. Knowing this how would you go about the building the motor remebering that I'm already running a stall thats around 2500 and I have 3.91 gears?
