LT1 cam gear If an electric water pump is used on an LT1 and the water pump driveshaft/gear are removed, can a standard SBC cam gear without the teeth for driving the stock water pump be used?

You can do that, but it has to be a timing gear for a factory roller camshaft. I prefer the GM single roller HD chain kit that the ZZ4 crate engines came with, I can get you a part number if you need it.

People have been doing this for years. If you have a 95+ optispark you can use a Cloyes made for TPI engines.
The hardest part is finding a plug for the timing cover. I gave up looking and siliconed a coin over it. It never leaked.

I was thinking of having the hole in the next one I do welded up. Trending Topics

The chain I normally run is a 12371043, it comes with the crank and cam gears, and the single roller chain. I think it was about $50-60 from GM. This setup is the same components as the "Extreme Duty LT1/LT4" timing chain kit, but you can only use it with an elec water pump since the water pump drive is not included.
Don't use a CompCams double roller timing chain for a hydraulic roller cam. They suck. 
Were I to do it over again, I'd use a Cloyes. More expensive, but less likely to have that happen. My poor LT1... Something with a solid center section.
I also used a quarter jbwelded in to the hole. Worked great.

I run this setup with a cloyes works great. Nothing tops the old school double-row timing chains nothing well for the price that is!! Sorry I don't have a part number. But I have a place you can order it from for like 50 bucks. Let me know and I'll get you the numbers.
