Serious question, not trying to be a crap slinger.

If a person wanted a big inch, low maintenance, consistent, reliable engine with 170MPH horsepower in a sub-2500lb car, and not need to be worked on for several hundred runs, they could call R-M and have one, with all new parts, in their driveway in a few days for a little over 20k.

If I wanted the same thing using a Mopar based wedge engine, who do I call, what will it cost, how long will I wait and what block will I use?
