Need 360 Block for 408 stroker build

Well guys, I got the complete engine and tranny out of a '74 motor home for $450! The engine is at a reputable machine shop that was recommended to me by my neighbor who has used him for some Mopar engine builds, one of which is a 440 Duster. I don't think they are all Mopar but what it looks like to me is that that is what they prefer to work on! Got there and they were dynoing a 426 hemi engine....that thing was loud! Also got the tranny to a guy that was recommended to me from the machine shop, says he just does it out of his garage and is great! I will let you guys know any further details, thanks for all the replies.
