Actually, our Vette's water pumps are neither short or long, they'll kinda in between. Neither will allow the belts to line up correctly. Therefore you'll have to use a Vette specific pump.

My 350 came from a truck (who knows where the original is) so I wonder which I have

What if you used "normal" SBC crank pully etc, it wouldn't matter then right? Or is that the problem, you can't use normal SBC pulleys?

I believe that's only true of early 70's and up - previous are "short".

Marshrat where exactly did you come up with this information?

from what i have been able to find out on the auto parts sites
the pump used on the 78 is a short pump as the guys above stated.
short or long is actually where the pump itself bolts to the block
