i am putting a 91 5.0 in my boat and i need to know what i can and cant remove from the engine. i dont need smog so can i rip that s*** off and use some type of block off plates. where can i find good performance parts (non eger)? what do i have to do to the ecu? i am kind of new to 5.0 but i have a good understanding. im sure im missing so much more but thanks for the help.
