I was wondering, what is the difference between the H.O. and the "regular" output? Now I know that the H.O. has about 325hp, but what is done differently? Is it different programming in the computer? Is it a different head?
My 03 SO has 250hp. The HO's have different injectors, oil spray to the bottom of the pistons for cooling and computer enhancements. Also the compression ratio is higher. Not sure if they get that with the head or a different piston.
