Does the LT4 Extreme duty timing chain set work on a 94 Opti with splined shaft drive?

where can I find, JUST the LT1 timing chain, and the chain only, and how much is the thing, and what is the part number

 

can someone please answer this?

 

No. Wont work with the non-vented opti. You can get the stock chain at one of the many GM dealerships in Houston. Go to the parts dept. Or Racenet or one of the other speedshops in town should be able to get you the stock chain.

 

If I was you id get an electric waterpump and a real timing chain like a cloyes double roller or equivalent, and those together can be had for about as much money as the weaker LT4 ED unit. Im not sure if you'd have to upgrade to the vented opti at the same time or not, cuz i have a 95, but thats what id do. hope this helps.

Actually, I have a brand new stock chain P/N 10128485 - unopened - still in the GM shrink wrap. I beleive they are about $30 - dont quote me - I forgot exactly what I paid for it. I'll sell it to you for $15 though, if you pick it up. I'll be out of town this weekend, but I'll be available during the weekdays next week. PM me if interested.

I decided to do the vented opti converstion, with elec water pump, and double roller, that's why I never used the stock chain. If you want to use the ED, Lt4, or Double roller, then yep, you've definitely got to do the vented opti converstion. I just went through this myself on my 93.

 

He would have to get the 95 vented opti and the 95 timing cover.

 

Well, if you're doing the coversion, you can also use the 96 or 97 cover if you can find one available - you just have to leave the Crank position sensor plug on, or cap the hole with a freeze plug.

 

thanks for the offer, but Id rather go to the parts store just becuase its convenient, unless you live close to seabrook, or clear lake, one more question, will a 95+ chain (not the gears) be the same as a 92-94?

 

Stock 93-97 chains are the same.

 

thanks a ton, that sure is a breathe saver, I was worried as hell I wouldnt be able to get a new chain, do you think the gears on a motor with 114,000 miles are worn out too?

 

I don't even have to think. Yes, they are. Get a chain and both gears.

 

DO NOT BUY AN LT4 TIMING SET FOR A PRE 95 LT1!!!!

it will not fit the little cam driven shaft, and wont fit with the cover either,......

 

I put a new factory chain back on mine. I did a search a while back, and found that all the changing/swapping isn't really worth the hassle. An Lt1 hardly ever has a timing chain failure...Unless...It's extremely high milage. A "good" chain will also fail under high milage conditions.

Nope, I'm all the way across town, on the westside.

As shoebox, mentioned - Definitely replace the gears too, if they've got 100k+ on them...
