small block water pump outlet right or left?

ok, i bought a new aluminum radiator and didnt realize the outlet on the bottom or the rad is on the left instead of the right how mine is now, before i painted it black. (yes i painted my aluminum rad. black) i havent found any water pumps that have a left side outlet like a big block everything ive seen is on the right side.... looking through the new mopar mag. in the article the budget blown small block they show a water pump that has a left side outlet! anyone know what these come on? i need to find one or find someone to alter the lower tank of my new rad.
Any help would be great, thanks everyone!
