The Moroso was technically designed for the Hemi cars. The bracket that comes with it is designed to bolt to the block very similar to the location of the BT can on the hemi trucks. It does not fit the trucks the same though which is why so many guys mount it up by the radiator. The downside to this IMO is that the extra hose lengths are not appealing to the eye, and I am not a fan of the added length or upward angle of the hoses. Ideally, you want the can to be level or slightly lower than where the hoses connect to the PCV and the TB. I cant help but think that oil is going to buildup inside the hose over time. That thick sludge BRH posted is nasty stuff.
How many miles have you put on yours so far? It may be worth pulling 1 of the hoses off to check inside. It has been warm these past few months, so you shouldn't have any of that thick junk in there just yet though.
