How to turn 302 into 347?

[zepherman]

I have been planning on building a fast fox body mustang for a while now. All I needed was enough money to buy a stock Mustang and a few thousand to throw into the motor. I had it all planned out as far as what i wanted to do as far as performance modifications go. Well, I have the money but now im thinking of stroking the bastard to a 347, and that throws all my plans out the window because I dont know what all goes into turning a 302 into a 347. I know the idea is to go with a crank that makes for a longer stroke, but what else is involved? what other stock parts have to be changed?
Any light shed on the subject would be greatly appreciated.
