Does anyone know if a Lycoming 0-320 E3D is a good choice for an RV-9A? This engine came out of a Cherokee 140 maybe a 1972 model. From what I can tell it is the same as an 0-320 E2D except for the prop bushings are 3/8 instead of 7/16 inch. So I am assuming the prop bolts on with 3/8 bolts. Both engines have the same front main bearing as an 0-235 it seems. I don't know if that is OK or if it makes any difference. I will put new cylinders on it and increase the HP to 160 if possible. The cylinders have the thicker base which I am told means you can increase the HP on that engine. I don't know if that means anything either since I will be using new cylinders. Any advice would be much appreciated.
Thanks
