Would anyone in USA give me some advice on the best way to get more horsepower from stock factory motor 5.7 ls1 without spending a fortune to get more horsepower and get into low 12 second or even 11 second quarter mile times I'd be very greatfull if anyone in USA that knows/can advice me of a great cheap way to achieve greater hp and be hidden so I can bolt on and not be seen by other people who have same 5.7 ls1 factory engines. My father ran 12s from 192cubic 6 cylinder i have a dream of 11s
