0-320 engine

I'm building a 32" wing span supercub with 1320 gross. what is the best model of 0-320 , a1a,a2d,etc ? has to be conical mount.

with 32" wingspan you are going to need more than 150hp to get it in the air

If you are going to stay LSA do you really need to go with an 0-320?

I'll be building it light , duplicating some of the carbon cub parts.

Look at the type certificate data sheet. It gives all the differences and the weights.

an A2B is probably gonna be the easiest to find that will fit the need!

Well I'll post here because I don't actually believe the weights I measured but for what it's worth: with bathroom scales: after weighing whole pallet and then pallet separately (ie minus tare) my 1956 O-320 (no a?? stamped on it) with both mags and wires, carb, old Delco-Remi starter, newer ?nav alternator, old style oil cooler, 8 spark plugs, carb heat box ,exhaust system, cooling baffles, hoses, cables (ie everything firewall forward minus engine mount, mount bolts and rubbers, prop,spinner and prop bolts) storage oil and descants in the plug holes, hollow crank shaft with plug in the end, came out to less than 300 pounds. I used 3 scales and made sure to weigh complete and tare in same locations on scales. I checked scales with known (but different) weights and they seemed fine. Still think that's light for a 150 horse stock engine. I'll be losing the starter, alternator etc and maybe go solid state on one mag (who am I kidding. I'll never spend the money and then I'd need an electrical system).

Talk to Bart at Aerosport Power. He built us an ECI O-320 B1B that puts out 180hp. Great engine!

Herre are some weights:
