I can't believe with all my Mopar books I can't find the main bore min-max size for a 400. Thanks for your help.



Well the stock-min size for the 400 is 4.342. As for max, less is better. Keep the bores as thick as possible. Dont try to gain CI with the bores.






Don't think that's what he's asking..
