Greetings, Planning on LB-7 replacement with LLY heads or complete LLY Engine as done in "I have seen the impossible"[has 60k on change out now].Know most things need to change from LLY to LB-7 short block to just replace heads but wondered about if LB-7 fuel rails will work with LLY lines to LLY injectors or will LLY fuel rails be required? Thanks in advance for reply with any info or help!! Later Jim
