replacing timing chain?

Re: replacing timing chain?
I mentioned this timing set a few times already.... it is a single non roller and if you search a little bit you will find more horror stories from people running that lunati timing set than the stock one, making it worse than stock?

i dunno, i think I am just going to order the stock timing set as much as a i dont really want to.. but on the bright side, since I am using nitrous, the car is actually not going to be pushing much more than 375 rwhp prolly 90% of the time unlike with a blower/turbo were the you're pushing a lot more power all the time.

The cloyes and lunati single non rollers aren't much better than stock if at all. The only timing set that will work for my car that isn't "stock" is the $500+ comp cams double roller and i'm not that sure it will work either. I really don't think the timing chain is going to be the first thing I am going to have to worry about breaking either.. more likely the trans and rear end.

Cloyes builds GM timing sets to GM spects. There vented opti set is much better than stock.It's a roller and has billett gears.It' the LT-4ED.

I can't argue with making something stronger such as a heavy duty timing set. But I won't defend it either as I have run and replaced the timing set with a stock timing set on my rebuild. I know quite a few people who have LT-1's that run nitrous with strokers and 350's. They or me have never had any problems running nitrous with the stock timing set. I won't say that stronger isn't better, but I have seen the stock timing sets run fine in numerous other LT-1's.

funny that you say that, not to sure if LS1's run a better timing set, but there is a ton of them around here running mid 11s and few even in the 10s running nitrous and blower setups and with their stock timing sets, granted it might not be the safest way to go, I haven't seen of heard of any horror stories out here with the stock timing sets.

Re: replacing timing chain?
I recently upgraded my '94 to the '95 opti and aftermarket timing chain. I highly suggest you do this now, because it is kind of a PITA to do with the engine in the car. It will come back to haunt you later on, just like it did to me.
Upon tear down, I found the stock timing chain stretched beyond belief, I am surprised it didn't come off! What a pile of **** the stock chain is. I would never trust that part again, it's just too important of a part to skimp on.
Basically in order to make the swap to a '95 opti, you will need to change the cam to get the longer dowel pin to drive the opti. Not a big deal if the motor is already out of the car.
You will need a '95 timing cover.
You can run a gm performance parts heavy duty chain with this combo or...
Run an electric water pump and install a standard double roller chain (I got a rollmaster from Scoggin Dickey). But the timing cover will need to be clearanced. I was lucky because my bro has a cnc shop. I had the cover machined. The top hole in the cover has to be covered also because the water pump is no longer driven mechanically.
