63 water pump autopsy and new pump observations
Got cover off of engine from car. Water pump has the smaller propeller as in the gates models. And, as you can see in picture, the propeller is set deeper into the cavity than the new pump. [See pictures]. However, the new pump has the propeller that is shown in owners manual..
And,,,the new WP is significantly heavier.
Would the raised propeller cause any concern.
I never had a cooling issue w the one in the car that i just took off.
The cardone unit that has been previuosly suggested is not available, at least were i hv looked. Rockauto, canter. Etc..and has the larger propellar. The new unit does not make any contact to the mating surface and spins freely.
Also put pictivre of timing chain as well for information.

I had sent him a picture of the new pump offset a while ago, and he thought it was fine, that was before I saw how deeply inset the old pump prop was vs the new. And the weight ddifference Just thought I'd throw it out as part of the journey.
Yes, I knew the engine had been rebuilt about 70k miles ago, 20 years I think.

The replacement pump looks fine. The front engine cover has the recess where the impeller sits. Bolt it up and spin the shaft to verify the clearance.

1963 RHS A/C kick panel - photos needed
Posted by SK on June 2, 2025 at 2:20pm 2 Comments 0 Likes
Could someone post front and back photos of the 1963 right-hand kick panel with A/C?
My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.
Many thanks,

Loud air moving sound within carb with cleaner removed
Posted by Dave Fehrle on March 23, 2024 at 3:23pm 8 Comments 1 Like
While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?
