Ok thanks for everyone's suggestions. Hopefully I'll find one I can fit or have one made. Before I got it this engine was sent to be worked over, and from everything I can tell by examining it. It should really run nice and smooth. The compression is excellent, and smooth, and if I look into the cylinders I can see where it's been polished. Also I can tell the engines been completely resealed. I'm going to run it up here in a couple of days to see how it does. I'm breaking in a new OS .40, and trying to balance the rotor on my MF480 so my engine testing palette is pretty full ATM.
