Larry,
No, I haven't looked at any of the specs. I was just doing a comparison in my head on the difference between the 2X4 motor vs. the single 4 motor. Seems like the early 283-220 motor is rated @215, and the 2X4 motor is 245. The carb is smaller on the early engine and it has less compression than the mid-60's version. I feel that the 215 is the best combo for a '57 Chevy. That manifold on the 245 motor is pretty bad IMO.
