Legal Eagle Flying Adventures

Information to consider regarding the V-Twin engines, (in general). If not for weight the big block V-twins, typically 32 to 40 hp, with a redrive would power the Legal Eagle. Our final firewall forward flying weight needs to be in 90 pound area, (this weight varies on the aircraft weight) this would include engine, mounts, prop, carbs, filters, bolts, everything forward of fire wall. The small block V-twin weight fits into what we need. Question is if we can get the Hp and torque matched to a prop that will power our machine. It would be nice to build a lighter weight LEXL with allowance to mount the big block V-twin.
