An extra 150 lbs payload, eh? And all by inserting an FM supplement and sticking a placard on! What kind of witchcraft is this?
Now, if Bell will supply me with new expanded faces for the TOT and TQ gauges which will allow me to lift this extra weight and still stay in the green, I'll be a happy camper.
Or better still, shoehorn the 407 motor and transmission in. A discreet badge on the bootlid just to signal your intent (PowerRanger maybe or 206BIIIGT?) , perhaps a couple of NACA ducts a-la Lamborghini Countach, subtly flared skid fairings and we're all set.
