Managed to get the water pump finished up this weekend.
The stock LT1 pump has the impeller on a shaft that is driven by the cam (timing chain) gear. Eliminating this and going to an electric pump meant that I could go to a gen 1 roller timing set. Which is significantly cheaper.
So I pressed the impeller shaft and bearing out of the pump housing (forgot to take a before picture). Then gave it a clean up.
The electric pump requires some clearance notches for installation.
So I notched out the housing and installed the plug to fill the old impeller shaft hole.
Then gave a coat of paint and installed the CSR Pump.
Then mounted it on the engine.
As you can see I started fitting up the new spark plug wires... Unfortunately, I ordered the stock LT1 plug set hoping it would work with the management system I bought. Nope no such luck, half the wires are too short. Oh bother... Anyone know how to make spark plug wires longer?
