ok, so I can't read the numbers to make sure I definitely have a 350, so what I need to know is are the pumps for 305's and 350's the same? Is it just a universal waterpump for SBC's?
Mine spins clockwise if that matters at all, thanks.

 

They're identical, just make sure the direction of rotation is right.

 

Edelbrock makes them too and they are not too bad. Heard good things about them and supposed to flow equally to both heads.

 

3rd Gen 305/350 use the same water pump.
