I want to use the Extreme Duty Timing Chain on my buildup. Something I didn't realize until talking with the Cloyes guys at a show is it can only be used on 95 and later LT1's. My question is since my car (94) has had the opti replaced by the factory with the new style opti, and I'm using a crane cam that comes with the longer dowel, do I still need to replace the distributor, timing cover, etc.? Or will it work with no problems.

Can someone shed some light on this for me? Let me know if there is any information I left out that could help answer my question.

Thanks!!!

 

Just F.Y.I.

You can throw on an electric waterpump (I like CSI) and a standard small block chevy Cloyes Double Roller timing chain (make sure to get the non-hex adjust) for less than the cost of the Extreme Duty Timing Chain.

You will end up with 10 extra HP from the water pump, and have a stronger timing chain. It's a better way to go!

 

how does a waterpump give you hp?

6.2 hp from the water pump. Cars making more HP, reving higher will see more gain. The faster you rev your engine, the faster you rotate the stock water pump and the more HP it takes. It has to spin fast enough at idle to move enough coolant. This means in the higher rpms, it is spinning faster than it needs to and therefore is taking more HP than it needs to. The electric one spins at one speed all the time, freeing up HP vs. the stock one at higher rpms!

 

The extreme duty LT4 set is just under $200. Can you get a ele pump and timeing set for that?

frmula1, the 10 hp comes from the engine not driving the h2o pump

 

oh so its less **** running off a chain or belt taking power from the motor?

 

I thought about the electric route, I'm just not convinced the reliability is there. I know they have been tested for something like 5500 hrs of continuous duty, but I've heard some horror stories.

Thanks for the reply!

 

I bought a ele pump, then sold it for the same reason. I don't want to be out in the middle of Bumf*ck and have a ele pump fail.

 

I wanna do the same thing, the electric pump is supossed to last for I thought 2500 hours, maybe its much more at 5000, but at any rate, I drive over 100 miles everyday, so mine wouldn't last very long, and as someone else mentioned there is no warning sign, it just stops and your outta luck. My stock pump lasted 7 years.

 

Where are you getting these chains for just under $200...best price I've seen has been $235...please advise.
