I0-360 on Zenith 750 super duty?

Is this a good motor for the super duty? I have one with prop with very low time. I can use lightweight starter and alternator to reduce weight. It should get down to 300lbs. Is this to heavy? Thanks

Weight should be close, but probably acceptable. They offer an O-360 kit for the Super Duty.

I fly an IO-360 in my SD with a 82" Sensenich ground adjustable prop. Take off and climb are great! It moves your CG forward but well within range, kinda nice not too worry as much about aft CG issues but the nose will drop below 35 mph on landings of you don't have weight in the back (yes, I have horz tail fences too). CHTs are up to 400 anytime it's over 75F outside, flights in 90F have been managed with more mixture/fuel and slightly power.
