Water pump outlet modifications

A 3/8 npt tap fit ours perfect. just happened to get lucky. lol the one "easy" thing the hemi presented for us.lol

Back when i had my magnum headed 408, i just walked into the parts store, bought a couple 90's, and ended up cutting one to fit. Thats probably your easiest option, despite the fact it's partially kinked...and not the prettiest thing.
