Is there a double roller timing chain on the market that can be used with a stock water pump for an LT4 motor?
Nope, not unless you want to remove the crankshaft position sensor (CPS) disc, add an earlier LT1 hub ('96 hub is shorter due to the CPS disc), and program out the codes that'll be set because the CPS "system" is no longer functional.
I was trying to stick with the factory H2O pump, since it is almost new. I will look into the extreme duty chain. Thanks.
Stick with a LT4 Extreme set up, its the best for retaining all the OE accessories. If your cam is something like a LT4 HOT Cam using GM springs and roller rockers then a LT4 roller chain setup is adequate. But for extra insurance the Extreme setup is the way to go.
