I've used several 440 Source water pump housing and they have been fine. Also used their water pumps.
The 440 source was under controversy many years ago for having small passages. I have one and it works fine but was also wondering if they have made changes to there casting. For this build I'm doing now, I want something I can pass off as stock appearing but not necessarily stock. the 440 source casting has there logo on it and not really liking that for this build.
