In answer to your question of what broke in the Hurricane, I have this to offer.  The last couple of days I have been working on it.  I found #5 rod broken off both sides where the heads of the rod bolts seat.  Arp bolts didn't break.  #5 piston is destroyed, and the cylinder wall cracked.  #1 rod and piston are damaged.  There is about a 3 square inch hole in the side of the block.  It broke out between two of the pan bolts, the pan flange and side are not damaged.  The scraper is demolished, the screen damaged.  The oil pickup tube is OK.  The cam was not touched.  The crank passed magnaflux, will need grinding to remove the nicks and burrs.  The other six rods passed magnaflux.  The six remaining pistons show no signs of cracks in the oil ring groove where the TRW pistons tend to crack.  So other than a little scuffing up of the parts, the engine is not bad.  Bearings and cylinder walls look good.  It's built Ford Tough!
