**600hp sbm block limit? Or is it bs!!**

I totally AGREE supershafts......

The ANSWER to your last question there....is Politics, and PROFIT.

The Dodge/Cummins partnership and the 5.9L and 6.7L is the perfect example of this.......Cummins 5.9/6.7L Diesels are far superior to either engine the competition offers.....but it is SOLEY OWNED by Cummins.....Chrysler COULD build and develope an equally Awesome Diesel plaform as the other manufacturers....but WHY? The most ROBUST and Durable Diesel is Produced by Cummins.....and its EASIER to maintain the POLITICS and PROFIT than to spend Millions in Research and Development only to find out the Simplest, Strongest, Most Durable platform has already been developed and they could only make a Variation of THE BEST and cost them precious time and money to learn that lesson.

Chrysler Corp......Kinda like Henry Ford, are FAR from Stupid.
