Gen1 4.7 Vs Gen2 4.7

Hi guys,
Newbie to the forum & i decided i need to learn more about my Gen1 4.7 motor.

im trying to figure out why the stock Gen2 has a sizeable proportion more in perfomance. ive read snippets & bits an pieces but no full answer really, be nice if all the info was under one thread.
is it a different cam? intake? is the lower end HP/TQ # similar? add your info guys as your know it. any external ref's are also welcome!

Bottom line, i want to mod my engine for better power & if any parts swapping can get me there.

Gen 2 has better cam and better heads. not sure what else I seen it mentioned before. you can do the super chips turner. I never thought it would be so good. It makes a ton of difference. also flyan ryan ported and pollished tb. exhaust cold air intake.
