if it goes its easy to replace.

 

www.oreillyauto.com > parts inquiry > i just want to shop > catalog > set vehicle information > engine & transmission > timming parts & camshaft

then just look on your results page for part number C3039 - should be $95.

 

when i put my cam in which is a ZZ9 from TPIS i kept the stock timing chain, got new springs that was it, the stock chain will hold alot, so you really dont have to get a stronger one unless you ant to spend the money.

 

i'm on a slight budget right now so I'm gonna just buy a new stocker I just sold 40 of my pto time at work so I can buy a new opti and gasket set etc.... damn I feel low

 

how much did allof that cost, cuz it should all be like 200 if that, at least thats what i paid for my opti and gaskets

 

I haven't actually purchased the gaskets and opti..the gasket set as stated on the thunder racing website is like 88.00.. I'm pretty sure I saw someone say a new vented opti is like 280 from Jason Cromer.. that still leaves me with over a 100 left over.. so that's going towards my timing chain.

 

i would shell out the money for a decent chain people break stockers and it isn't that rare either. If that happens get ready to spend a lot of money to fix it.

 

yea is there a link to that cloyes timing chain kit.i was just in there and i put a stocker timing chain and gears in it but when i go back in that cloes kit sounds sweet.

 

nevermind

 

will that cloyes chain work on the non vented opti(94)and doesnt the extreme lt4 chain only work with the vented optis?someone explain.

 

Do all of the aftermarket chains require an electric water pump? I'm going to be doing an LT1 build-up in my garage over the winter and I would prefer to stay away from electrics myself.

 

Thanks for the advice, i'm saving up for the lt4 timing chain.. that doesn't need a electric water pump, does it?
