I am guaging interest on a product that I have designed and tested that will allow you to run a '95-'97 (vented opti) chain on a '93-'94 (non vented) opti.

This would allow you to run a double roller such as the LT4 timing chain without having to change over your entire set-up. Let me know if anyone is interested and I will look into producing.

 

you need to explain the product a little better than that.

How and where you going to put the splines? whats the cost?

 

I would be interested, but a few questions (getting ready to do cam,rr's,timing set,springs,otpi,elec w.p.)....
How much?
How long till ready?
details of the product?
Thanks

 

yeah. i agree with the two posts above, need more info and would also be interested.

 

why would you want to run a non vented opti, and there is no good reason to run any other chain than a stock one, if you do want to spend the extra money on a aftermarket chain then why cheap out on the opti

 

I'm not sure of the exact cost at this point, I wanted to see if their was a market for it before I went and invested in trying to create parts. It is basically a plate that sits in the recess of the timing chain that is secured by the 3 cam bolts. It allows you to run the splined pin, with basically any timing chain.

Actually their is very good reason. This would be for all the guys that are already running a non-vented opti. If your non-vented opti works and functions just fine; Why spend $500+ to replace your timing cover, belt, opti, etc when you can just use this and have the benefit of a roller chain and save $$$. Not to mention that it is fairly easy to "vent" a non-vented opti if you choose to do so.

 

i dont see the benefit of going with a roller chain anyway

 

MSD cap and rotor makes the "unvented" vented which means less reason to swap to the stock vented setup.

I tend to be in the "stock chain is very good" camp BUT I think some options are a good thing especially for a setup like the unvented with so few choices.

I am going to guess though that it wont be a cheap piece to machine, pretty tight tolerances involved to keep timing accurate. Good Luck.
