Yup, it was a $9-10K upgrade and should make 425 or 430, so calling it a 420 is pretty close. It's an absolute beast and really not much worse on fuel than any carbed pcm 351/5.8L
They also are reliable as hell, you just don't find many of them due to the upgrade cost. They are a bit louder, but if you don't like it, throw on a fresh air system. And to answer the OP's question... HELL NO it isn't overkill! If you thinks it's overkill, you have problems
