Ok I have a lq4 out of a 2007 chevy classic that I'm putting into my 2001 firebird with huron speed truck mani single turbo kit. Just need help with finding a double roller timing set for this and any info on what may need to be modified or changed to make it work i.e. shimmed oil pump/timing cover different timing cover.... Should I just stay with stock timing set up and just replace the old chain please someone help. Last thing I need to order before I can start my build.
