Quote: so nobody line bores?i thaught there was some debate as to it being better than grinding the crank?
anyone using a cast crank?
You can do that with a 400 block , but a 383 has thinner main webbing and it's not a good idea. 440Jim line bored his 400 block out to RB main size for a stronger crank, better main bearing selection and better crank selection at the time he did it .
