In my search results I found a reference to a vortec style timing cover without the sensor hole. It will fit over the reluctor ring . I don't want to buy a new balancer. Anyone know of the part number for this cover? Thanks for any help you can give me.

 

The vortec plastic timing chain cover, part number 12562818, has the hole for the sensor plugged. This cover is used on ZZ4 crate engines and vortec truck blocks when the crankshaft sensor is not used. It comes with bolts and the crankshaft seal is already installed. I just got one from SDPC for $16.95

 

I bought one of those from the GM dealer before I knew you could run a regular timing cover w/o FI. $53.00!!
