So im doing an Lq9 408 build. ill be using a ported Ls3 oil pump. i know there are differences between LS O-rings between the truck and cars (red vs blue). i plan to go buy both o-rings just in case. how can i tell which one will really be needed. is it a difference in the tube sizes or the wall size of the pump?

more than likely ill need blue since i have an Fbody tube, and Ls3 car pump. but i just want to be safe than sorry by getting both.

Not sure how much this'll help, but when I put a new pump in I used the blue o-ring. My motor isn't a 408 tho.
