![]() The most common 347 is a 3.4 crank with a 4.030 bore. The most common 331 is a 3.25 crank with a 4.030 bore. Most companies use a 5.400 rod, but I have seen some use a 5.315. On a normal street motor, it will make no difference.
If you want a 331, I have a 3.25 4340 forged crank for sale. Its in excellent condition. Andy
