I am thinking about redoing my 5.3l vortec, I want to have more power than stock, get as good or better gas mileage than before and try not to get too rediculous spending money. any suggestions?? i am thinking of rebuilding it with a regular kit and putting a K&N intake kit with a chip on it. i may do other engine work depending on the factors above... let me know any suggestions from mild to wild, im not sure what i want to do with it yet.
