They had to replace a LOT of OEM stuff to make this work. But they did it. I've always felt that the B58 short block is fairly stout.....it's everything else on the engine that makes me cringe.
Personally I'd rather see development in the opposite direction of "Simplify and add lightness." The B58 is probably the lightest commonly-available Inline-6. Develop some parts to make it run for 30 years with just an oil change please. But hey, I don't live in a country where every road is basically an airstrip and everyone wants 4-digit horsepower so they can get airborne. So my priorities are a LITTLE different.....shrug
