I've had 440Source ones. Many gave them a bad rap claiming the water passages were to small causing overheating. Yeah, they were a little small ... so I used a die grinder and opened them up. At the time you couldn't beat the price and some people are just "CHEAP CHINESE JUNK haters" and will complain about anything. I've see other brands - Mancini have most of them on display at shows they attend. Personally I still like the Mopar one best of all.

Have you ever ask any of the hundreds of companies that have their products made in China why they do that?
The answer is the same reasons American companies move their manufacturing to Mexico, Canada, India, and many small African countries now and so on, it's all about the bottom line and how much money they can make

The MP housing was a little overpriced and maybe not perfect, but was cast and machined in California,
and was a made in USA product. Didn't matter how many times I'd explain that: Most people don't care and just want all the cheapest stuff they can possibly find. I usually grab them when they come along at a reasonable price, but if they weren't affordable/available I'd run factory iron without a second thought.
