really not worth it to swap our v6 to the v8 engine... u have to change so many things. Would be cheaper sellin the v6 and buying a v8 gt or my favorite car that i just brought
trans am ls1.
Now for the question... it sounds like the car still runs fine just needs some fix ups here and there. leaks can be fixed pretty easily, plus when u turn on the ac ur always gonna accel a lil slower. Your taking hp away from the car. the low rpm i say its time for a tune up. change ur plug AND wiring :P. 180k miles is alot so just ride it out and invest ur money in getting another car or similiar engine as ours.
my 2003 is running at 131k miles just hit today.
