Thanks for info Topside. Obviously WOT sound is not priority on this being that it's mostly stock (headers, dual exhausts - no cats - no air pump) heavy truck but that sound is nice to hear every now and then and is music to my Mopar ears.

2boltmain, I get where you're coming from and may just splurge a bit for simplicity and reliability and when the 440 comes use the carb on something else or sell.
