Mopar made three different lengths on the runners by removing the dividers between the runners, I think the last version used the shortest dividers scope
As far as the power band I think they were all low RPM performers, under 4200 RPKM for peak HP and I think around 3200 to 3600 RPM for peak torque, maybe I'm wrong on the numbers so make sure and check them before deciding twocents
