1999 vs 2000 15hp difference?
So I was doing some research today and found that the 1999 5.3L motors had 15 less hp than the 2000 5.3L motors (270hp vs 285hp). Does anybody know why there is a difference?
I'm swapping my 280,000mi 2000 5.3 out for a 18,000mi 1999 5.3. Its gonna **** me off if the new motor is gonna drop my power!

my 99 is a freaking turd as well,but i would speculate that the cam is retarded from the factory....
why do i assume this?
my 03 made 250hp and would walk all over my 99
my 99 made 260hp at the top of the "power band"
so do yourself a favor,install a cam, upgrade injectors and put it in a new fuel pump,im pretty sure the 99 pump is on the verge of its death soon.
basic bolt-ons of coarse.

Well I don't have the $$$ for the cam swap right now. The engine swap is being rushed since I just found out I'm moving from FL to CA in a month. I do have a 02 5.3 I can rob the injectors from though!
