I told him that it is my understanding that many Pontiac guys have proven that a cast impeller with tall veins and a properly fitted divider plate results in lower engine temp's. He told me that he can give me whatever I want so if I want a cast impeller with tall veins it's no problem... but, he did say that the tall veins are prone to bits breaking off so he wanted to warn me about that.
Unfortunately I have an early 69 short pump so he doesn't have a core but as long as I don't need an original I can give him any short casting and he'll rebuild it with a cast impeller.

Wow, that surprises me that he said that. He never gave me any indication that he did not believe in the cast impellers. He also acted like it was no big deal and that he had a lot of them. Oh well, you never know what line people give you to make a sell.
