We also didn't like the
oil ring problem with the 347 and decided to go with the 331. It is a sportsman block, scat 4340 forged crank, forged JE pistons, ported and polished aluminum World Products Heads, comp cams custom grind .560" lift 230 duration, comp cams roller rockers, 10.4:1 compression. It should come out around 420 hp and about the same in torque. We are gonna put it on the dyno after it is together so i can post real results here in a couple of weeks.
