For what it's worth...when I was checking out engines, I found that Superior had recalls on several parts, including their new sump. I ended up going with the Titan kit engine from ECI through AERO Inc. Light Plane Maintenance (LPM) rated the ECI cylinders higher. Another extra was AERO's forward servo sump, which I was able to substitute for the regular sump. Their kit was pretty good; however, there were a few pieces missing, mostly nuts and bolts and a couple of large O rings for the intake manifolds. They were very quick to make everything right, so no real complaints. They also offer an assembled engine. If I remember correctly the price was about the same as Superior. ECI's Titan seems to be a true clone of the Lycoming with very little change from the original.
