Hi=20 John,

I can't imagine there's much weight = difference=20 between the rest of the FWF items of an O-320, and the = IO-240. =20 If it's heavier, the CG can possibly be worked out by moving the = battery, or=20 remote mounting the radiator, but you'll still be overweight in=20 general. You might want to ask about the folks that put = IO-240's in=20 them. They may have already had to take all the CG measures, = which=20 will leave you without as many options.

Good=20 luck,
