engine dimensions

hi.
first time on this site
i am trying to choose a engine to go in a project car its a ford sierra 2 door
what I am looking for is dimensions of the sb and bb so I can decide which one will fit also the weight of each, a technical drawing with measurments would be ideal
any one help ?
thanks

Well, heres dimensions for the SBC among others:

For BBC, you'll have to look :p

Thanks, that is the best webpage page I have found yet. I am really surprized that someone doesn't have some rough dimisioned drawings of various engines.

Anyone have any better info? Thanks!

P.S. I love bumping old threads to prove I use the search button;)
