Part # LUN-93094, its 108 and its for the non vented optis. Any one use it or know any thing about it? I have a brand new complete GM opti on the car as is, I'd like to reuse it and I dont want to spend any more money going over to the vented opti stuff If I dont have to.

I've been thinking about ordering one myself, but as far as lunati goes you can rest assure that its a good quality product!

Thats what I was thinking, the only other option is that Comp Chain for non vented and it costs a ton of money, would be cheaper to just go vented an a LT4 chain. That Lunati chain doesnt cost much at all, I would just hope its a little better than a stock timing chain. I dont think I'm going any thing to radical, just want a nice rough cammy idle

I would use a reg. old SBC double roller timing chain and install an elec. water pump. Just my .02

i was wanting to do the sbc double roller too but have the non-vented opti. so will the chain clear the timing cover that i have?

You need to convert to the new style opti to use the double roller. The opti is driven differently with the older style (hence the length difference in cam dowel pins - which you will also need to swap).

ok, thanks. guess i will stick with what i have since i just bought a new opti also.

I think a guy over at camaroz28.com just broke one. He didn't replace the gears with it though and the cam gear ate teeth.

If you do go double roller, be careful which one you get.

This is a CompCams unit, for a hydraulic roller motor.

I could not find anything else wrong with the motor other than the cam gear. Everything else was fine. So my assumption is that the cam gear failed.

The Cloyes has a solid center section for the cam gear.
