We are in the process of putting the motor together and we came to a little bit of a snag. I have an MSD opti non-vented, but the timing chain set I have is a Cloyes double roller that will only work with vented opti's. What timing chain do you guys suggest and where can I get one that will work with a non-vented opti? Thanks a bunch I need to try to get one here by next weekend so my weekend isn't a waste, lol.

Your options are fairly limited with the non-vented opti setup. You're probably better off with an OEM replacement chain. Either that or converting to a vented setup.

Lunati also makes a chain that works with the non-vented setup, AFAIK.

Stock OEM replacement is just fine.

I'm thinking I'll go with the Lunati piece some guys have said it's pretty much identical to the stock one. Where and how much would I get an oem replacement just in case I go that route?

Just get these OEM replacements and call it good. GMPARTSDIRECT has the best pricing.

OEM would work real good

U can get a Cloyes stock replacement from O'Riellys for under $125. They gears have a GM stamp on them. Cheapest I found so far without buying off the internet.

Or he could buy the stock replacement off gmpartsdirect for under $85

Oh hell yeah, can't beat that price. I gotta get over my paranoia and set-up a paypal.

Thanks for the help guys. I'm going to give it today to think it over and see but at least I have options.

HAHA I understand where you are coming from. You'll be fine "right after I buy a Nitrous set up on your account"

How hard is it to change. My distributor is already pulled. Do u have to remove the oil pan or have any special tools?

OEM chain is more then sufficiant

You need to remove the crank snout (requires a puller) and then remove the timing cover. You may need to drop the front of the oil pan slightly to avoid tearing the oil pan gasket (not a fun job to do if you do tear it).Once the timing cover is off you'll need another puller (claw-type) to remove the crank gear.

And I'm guessing those puller's are not cheap. Is the one to remove the crank snout different than the one used to pull the harmonic balancer?

RamAir95TA

Yes, they are different. The one used to pull the crank gear/balancer looks like this...



...and the one to pull the crank hub looks like this:



Both of these can be rented at pretty much any part store.

I got to use the GM "J" tool to remove and reinstall my crank hub once, soo easy. Wish I had one. Now I just make due with the 3 claw puller and a custom made installer.

Hey I know you guys were talking about the oem being the way to go but what about the Lunati 93094? It looks like the stock piece and is like 15 bucks more, I figure since I have to make a summit/jegs order anyway and it'll work I'll get this one. Whatcha think?

That timing set is only compatible with vented, non-spline drive optis. The OP has a '94.

I am the OP, lol. Anyways I was wondering because summit says it's for 92-93, I wonder why not 94?
