There is all kind of speculation in this thread but one thing I do know is that engine will never be a dog. It may not make good power in street parameters but a dog it will never be. If you feed it and keep it up it will be one hot small block. Just not what most people would consider a street engine and therein lies the problem. Most people aren't willing, or at least they think you aren't willing to put the effort into what it takes to make that engine perform and live in a street environment.
Screw them, this is the very reason why you don't see hot Mopar small blocks on the street, everyone is afraid to go for it, while the brand x guys are building and driving what you Mopar guys won't.
