5.3 to 5.7 So please bare with me on this. I am new to the LS family
I have a 2000 4.8/5.3 block with 862 heads. I plan to buy a complete build kit from WS6Store to include the hot cam kit. Here is my question. I was thinking about boring it out to 5.7, but if i do that what needs to be changed, besides the pistons, cam is planned to be changed. I am specifically wondering about the injectors, throttle body, got to send the brain in to get flashed anyways, so i would make sure the engine data is given to them.
Any help with what must be changed is appreciated.
PS i have done a few searches on this and could not find the data.

Thanks for the input. I should note that my motor is currently a 4.8, but i found a correct 5.3 crank 12552216 and a set of full floating rods. I was able to find the injectors are the same from 4.8 to 5.3 but not sure about the throttle body.
