Jay,
With peak torque is at 3200 RPM and peak power at 5200 RPM that suggests a 2000 RPM spread.
I'm certainly no expert here but based on my observations that doesn't look right.
I've already posted a few examples but here are two more....
Another 4.5" stroke
Peak power at 7000 RPM
Peak power at TQ at 5500 RPM
1500 RPM spread.

Here on this 4.5" stroke combination the spread was 1000 RPM and as much as 1400 RPM depending on the intake/carb set up.
