Scroll down to page 9. Your 350 is option LS9 on your SPID right?
Also your engine assy stamp might tell. It's stamped on the block on a pad just in front of the passenger side head. Get the suffix code at the end. (last 3 letters)
GREAT website! Downloaded the PDF and will save that for future reference. Thanks!
