I know you posted this tongue in cheek, but you are absolutely right, Bob. Chevy engines are the least expensive to play with, and GM didn't make running changes every 6 months like Ford does. GM has kept the same basic design, with some updates, over the years, and parts are available everywhere.

As I've mentioned before, I lean toward Ford and Olds engines, but MAN, do I have a lot of respect for the 350 Vortec I had in my 23. That thing just purred along, always got me home, and didn't cost an arm and leg to build. No question us Ford guys pay for our loyalty.

Don the more I ponder this the more I wonder if the high rpms may have created some cavitation eating the pump up so to speak. I've seen it happen to propellers on boat. Just a thought.

Me too, Steve. For sure something reshaped that flat plate into a bowl shape. I know it was perfectly flat to start with because I had the back of the pump off to replace that blown gasket in Daytona and looked it over carefully. I was trying to see if I could determine the direction the pump was supposed to go (I was afraid they inadvertently shipped me a serpentine version) so I was peering under that plate to try to see how the vanes were aimed.

When I pulled the back off when we were home there was this little cupped thing inside there, instead of the flat plate. It just amazes me that whatever forces were working on it created an almost perfect lip around the edge. I would have expected the plate to be all chewed up, but not uniformly distorted like it was. I guess I'll never know.

Yep Chevys are cheap to build but Fords go faster !!!
