I have a GM AC- DELCO non-vented opti with less than 1000 mile on it. I am selling it due to a 383 build up and I am going to use the true roller timing chain and csi electric waterpump. It is on ebay right now for 5.00 and I will guarantee the opti is still like brand new. You can tell by looking at it it has not been used long. Here is the link to the auction.
