what timing chain to go with im in the middle of putting a cc306 cam in my car and was thinking about getting the stock chain out and replacing it with a bigger chain. should i do that? and if so what chain should i use. also the stock chain has 40,000 miles on it and its a 94.
thanks
thanks
Just stick to a new OEM timing chain and sprocket. No need to invest into the Double roller/HD chain.
GM # 10128349 (sprocket)
GM# 10128485 (chain)
GM# 101228346 (CRANKSHAFT SPROCKET)

is it a stock lt4 chain and they call it a lt4 HD chain? and can i get it at a dealer or do i need to go thru summit or what not?
The chain and sprockets wear together, no sense in throwing on a brand new chain on worn sprockets. You will accelerate the wear on the new chain. While you might be able to get away with it, I wouldn't recommend it, it's a peace of mind thing.

+1 There is really no need for a heavy duty chian set. I have heard stories of them actually breaking. Stick to the OEM version as mentioned

Verdad Gallardo I have heard that this is a good product:
Lunati Timing Set
http://store.summitracing.com/partde...4&autoview=sku
Probably just as good as the OEM replacement timing set, which should be sufficient for 99% of applications.

Well the Lunati set is only 10 bucks more. If there's no rush, the OEM set from GMpartsdirect would be your best bet, I think it takes a little over a week for them to ship. If you needed it quick, you could order the Lunati set and have it arrive in 3 days or less.
^^True. Summit is basically waiting at your front door W/ your products after you hang up with them..lol Great place to do business with. If you are not in a hurry do the factory one. If you are in a need for it asap look into the other (which I have haven't heard much about)
I believe there are some minor modifications that will need to be done...I could be wrong IDK...As far as it being better, it's a matter of opinion. I personally wouldn't do one unless I had the motor out and was rebuilding it to something much bigger. For what you are doing the stock replacement will be more then sufficient
the LT4 Extreme Duty set is a much more substantial piece, I have pics of the stock LT1 and the LT4 ED side by side but it is on my other computer, there is really no comparison. As for installation, there is no modifications that need to be made but you do have to replace the water pump drive gear with the one that comes with the set, if you are leaving the intake on you need a special puller to pull it out of the block then press the new gear on the shaft, other than that it is a direct bolt on.
For the dollar and for his application it's really not worth it imo. How many of you guys have heard or seen a thread on here about a timing chain incident? I haven't seen one...well I take that back. I saw one on here a long time ago and it was on a guys LT4 chain that didn't work out so well.

Some have seemed to miss the fact that he said he has a 1994. In that case, he has a non-vented opti (I saw nothing about a vented conversion). So...he basically can use only a stock (or stock type) set that has the provision in the cam gear to turn his optispark. An LT4 ED will not work.
Elliot's94Z's list is correct for stock 94 components.
