Trying to get info on your setup. Just how I’d like to do mine. Any issues with factory magnum brackets with rpm intake is what I’m looking into. Factory tall t-stat housing?
Only input I can give it is almost certainly has to be the right RPM intake. The #7577 is Magnum specific and is the only one that put's the thermostat in the right place to fit the AC compressor and alternator. Just in case you didn't know.
