The 341 has a bigger bore. What is wrong with the 330. If it has a cracked cylinder wall, you may consider sleeving it. These engines are getting tough to find. If there is crank damage, you may still be OK. I have a crank that had to be ground .040" under to clean it up. Bearings that small aren't available for the Desoto, so you can substitute Pontiac rods for which you can get the bearings. What is the motor going into? I'd like photos of your project if possible at crossram5@msn.com. Thank you, Bill
