427 stroker build

[ProStreet71]

Hey guys, I am helping my buddy build a 427 sbc. He got a good deal on a new Dart Little M block. $1500!!!! We are searching for parts at the moment. Marv gave some great advice in another thread on this same subject. Now the question is, are these blocks ready to use? Do they need any final machining? I am sure it will need to be finish bored for what ever piston we use. Will probably deck to "0 deck". Will it except a 4" stroke without clearancing? Thanks for any help!
