Did you fish out all the impeller bits from the cooling system?

[CradGen2]

I agree with chexi. Also make sure you don't have air leaks in the flush pro

Make sure you didn't put the pump on upside down . If its a 351 the pump should be mounted with the hoses on the block side.

Yes, definitely check the orientation of the pump (if you took the pump completely off when changing the impeller). On these old Fords it is possible to put them in upside down, in which case they spin but you get no water to the engine. Maybe not a bad idea to check just in case anyway. The last person might have gotten it wrong.
