DYNO Numbers for Baggers???
74 hp
84 tq
I am happy with the numbers plus I have more feel of the pants power and it runs a little cooler with the PCV. Since the addition of the PCV and dyno tune I have added cooler with fan again a bigger drop in oil temperature.......Bob

I have a Headquarters cam that does exactly that for my motor now.
I'm running 10.37:1 cold static compression. My torque hits 100 ft lbs at 2600 rpm's and doesn't drop below 100 untill 4750. My HP & torque cross each other at 95/95 @5250 My HP hits 100 at 5700 rpm's.
I have a good tune for the price that I paid. It dynoed @ 100/102.5. Keep in mind though, I do not have a proven engine configuration. I thrrew this mut motor together with my fingers crossed. I did research the engine builders who's products I'm using though.
Here's my cam specs so that you can use that for a comparison. My cam is an HQ-0039G.
intake lift: .580 timing: 20/36 duration: 236
exhaust lift: .530 tiiming: 52/24 duration: 256
The intake is high lift short duration and the exhaust is mid lift longer duration. The timing of the intake is such that I get great low end and midrange torque and the shorter lift and longer exhaust duration brings out the horses on the top end. I get the best of both worlds. Of course some of the horses are achieved with a higher compression ratio too.
That's something for you to chew on.

Get rid of the true duals and you can get back some of your low end torque and even increase your top end with that 258. Swap out the TDs for a D&D FatCat and my guess is you'll raise the torque to 110 and raise the HP to 105 but more importantly you'll lower the point that the torque kicks in by 300-500 rpms.
That's the only way I can think of to get your low-end torque back without "cracking" the motor.
