[QUOTE="MalcolmV8, post: 15067715, member: 8854"] The oil pump advice above is good. I spent $400 myself on a pump and then later realized I could have just purchased billet gears and installed them myself. I've never seen a need for billet chain tensioners. Seems like bling more than anything. If you have the new style plastic primary tensioners with no ratchet setup toss them and get the earlier version cast metal ones with a ratchet. Not only are the stronger but they hold tension on the chains more consistently as the oil pressure fluctuates. I was told the GT500 secondary chains are stronger than stock and don't snap. I put a set of those on because I have heavier aftermarket valve springs with more aggressive cams. One thing I did invest in this department is the Cobra Engineering secondary tensioner adapter for the passenger's side head. It flips it around to be on the correct side of the chain. If you look at the other three tensioners on the entire chain setup they all tension the trailing or "slack" side of the chain. The exception is the passenger's side head which tensions the leading edge or pulling side and as a result as the tensioner flexes in and out it will be constantly changing the cam timing between the passenger's intake and exhaust cams. Not good at all. [url]http://www.cobraengineering.net/tensioner.html[/url] [/QUOTE]
