Been there done that... From Experience:
The 250 is slightly different in the front of the engine than the
tr6. The water punps are technically interchangable but the pulley is
pressed further back than on the 6. Also the pump drive shaft may be a
different diameter.
But the fix is: Pull the pump and press the pulley further down the
shaft. Make sure there's room to slip the nuts and washers on.

as far as corvairs, well it is made by GM and we all know what GM stands for.
