some quotes from that article:
"What we found is a ridiculously strong-looking engine that should survive many a quarter mile."
"With a short deadline on engine development, there was no time to prove the durability of low-cost, marginal-strength parts. Where typical engine development teams would spend time whittling away pennies finding the least expensive design that could meet durability targets, the turbo 2.4 team just threw in stronger parts and more expensive materials, cost be damned."
"The cast-iron block looks extremely stout, with a closed deck on top and a very strong split crankcase. Rather than individual main bearing caps, or even caps joined by a main bearing girdle, the block simply extends past the crank and is split right down the crank centerline. The bottom half (called the bedplate) incorporates all the main bearing caps. In addition to improved strength, this design offers reduced noise and vibration, so it's becoming fairly common in modern engine design."
"The SRT-4 drag teams are rumored to be making between 800 and 1200 hp on the stock crank (and stock block and bedplate), so we figure it's strong enough."
