To be honest, the Mopar and the Chevy were pretty much even, aside from the low rpm levels. With better heads, the Mopar 383/392 would have left the Chevy in the dust.
The thing that they didn't bring up is that the Mopar will go for 200,000 miles, easy. The Chevy 383, being a stroker, will be lucky to go 50,000 miles. Not important I suppose, for a car that is driven on weekends or to car shows only, much more important for a daily driver.
