does the roushstage 2 come stock with blue injectors? i got orange when i bought my stage 2. also i just read this post(https://mustangforums.com/m_2595637/tm.htm) and it looks as if this guy's engine isnt orginal because of some writing on the timing cover, ive got some writing on my cover too. it freaked me out so bad that i bought a carfax and everything turned out ok, but i dont trust that. it just has a J and H written in blue. anyone know what that is? i paid a lot of money for this roush, i would hate for it to not have all the original parts. couldnt the dealer get in trouble if they knew it wasnt the orginial engine and didnt tell you?
