I asked my engine builder about this yesterday - I told him I wanted a Cloyes double roller put on my LT1 and he informed me it wasn't possible. I noticed a couple guys on the forum had them in their signatures but I guess they must have done the electric water pump conversion. I really hope I don't run into trouble with my timing chain because I'll be running the LT4 Hot Cam.

With using the stock W/P you must use an LT1/4 timing set. Cloyes makes a couple but none are double rollers. With the LT4 even if you went to an electric pump it would still be a problem because of the CPS as GS96 stated. I have seen it done on a LT4 but it took a bit of machining to get the DR to work with the CPS. For a normal LT1 as long as you go with an electric W/P is a straight bolt in item
