SOHC Times/power??

[Bossxr8]

I don't think the internals are balanced properly like they are on the Boss motors, they are slotted straight into Falcons from the crate. Since FPV hand assemble the Boss motors they balance the crank at the same time, and if I can remember correctly the 290 goes a step further with the whole rotating assembly balanced as well. This will have something to do with it as would the limitations of the heads. I think the power would drop off after 5000rpm so it may not be worth revving them out, as said earlier they are truck motors designed for low and mid range torque.
