Hey guys, I have all my parts from Summit and I was looking at what I ordered. I must have read something wrong on one of the posts. I have a 1995 Impala and need a timing chain. I don't need the water pump drive because I'm electric. Summit sent me a Cloyes 3157. There is no provision to drive the opti off the cam gear. It sure appears that I've ordered the wrong part. Is there a true roller timing chain set that will work that doesn't cost and arm and a leg. A single roller would be best because I really don't want to grind on the front cover. Does anyone have part numbers for what I need.

Thanks and have a great day. --Bill--

 

I'm confused. You should have a vented opti. It drives off the cam dowel pin. So, the gear has really nothing to do with it.

A 3157 is just a single rather than a double roller. I don't see why it would not work. I think others have used it.
