How does cid make power?

Damn. How big was the bore on the Chrysler? And what was the bore on the Chevy?

Then compare the torque curves.

383 Chevy was a Blueprint short, so I think 4.030/3.75. The Mopar was +.060 (if I remember right), and actually 391. (Eight cu.in don't mean dick, imo), so 4.310/3.38.
So, more bore, less stroke for the mope, and still killed the chevies torque.
Edit Chevy was .040, so 385, mope was .060, so 394.
