[QUOTE="Catmonkey, post: 16550399, member: 124025"] L&M sells the billet secondary sprockets that look identical to the ones the Cloyes used to make and sell at 20% of what L&M is currently asking. They would be on top of my list of timing upgrades, but is not exactly a budget item at $400. I think the billet secondary tensioners would be second, which isn't exactly budget friendly either. I'd at least do passenger side, if you can't put both with your budget constraints. I did these upgrades a while back, so I don't know what's available for secondary chains, but get the best one out there. After what your engine has been through, whatever you don't replace, go with new parts for the primary chains and sprockets. The only aftermarket upgrade on the primary side for the GT500 is the billet crank gear, or at least used to be when I did mine. Since that gear drives both chains, and in effect all 4 cams, I think it's a good place for a billet component. OPG would be a definite, if your pump doesn't already have them. With the engine trauma, I'd probably replace them regardless. That component is too critical for the whole engine, which will still be a big investment given your budget constraints. Jay mentioned the pin upgrades, but you're not running an aluminum block and I don't think it's as critical on an iron block. The problem with the pins used in the aluminum block is they screw in and the threaded portion of the OEM pin is undersized in relation to the rest of the pin. Your pins are pressed into the block and are the same o.d. as the rest of the pin. [/QUOTE]
