If most all of those components are stock, you are probably looking at 9:1 to 9.5:1 CR.  Depending on programming, you may be ok, but you would definitely have to get a good tune! _____________________________ Kyle- 04 Rainier My Restoration Projects Please Do Not PM for Tech Help (in reply to slammed) Post #: 6
