versions set alot of records basically if you have easy access to one and would rather have a big block mopar thats not a 440 then go for it otherwise a 440 would be alot easier to find and get some parts for, such as pistons as mentioned above plus a 440 would just have more balls equally built...not that you could honestly say a built 413 would be lacking in that department #5 (permalink) 07-28-
