Stock 5.3/6.0 injectors vs Stock F-bod ones?

How large are these injectors per application for like '00+ vehicles?

5.3

6.0

5.7

I'm thinkin' it'd be cheaper to swap to an LS1/6 intake w/ a set of their stock injectors (as they make close to 300rwhp stock) and I'd assume I'd be around 90% IDC on 5.3 injectors at 300rwhp (what I'm thinking taht 218/222 cam will do for me.)

i know for a fact that the 4.8-5.3-6.0 lq4's are all the same. i thought that the lq9 and 5.7 were the same and they are bigger.
