The 318/392 has a longer stroke than the modern 392. Over 4” bore. I wonder how the torque is going to come on. 318/392 will it be a better low revving motor 5600? Or more of a 6k+
Depending on top end, especially heads and cam. If you can get the small bore/long stroke to displace enough fuel and air over time (CFMs) the engine will rev, just a bigger bore shorter is more suited to higher rpms.
