well i crashed my car!

!!!! lucky my engine gear box drive train diff all survived! so im goin 2 get a cheap body n swap it all over. now im thinking of making it better while all the stuff will be out. at the moment ive got a 5.7l ls1 6speed and thinking of selling it and gettin a 6l
Will the engine bolt straight on the existing engine mounts/gearbox?
how much are second hand 6l engines? + where to get
an average price ls1s are selling for.
will the 5.7 computer be right or will i have to get a new 6l computer?
thanx every1. if it is too hard i might just get a cam and heads or something for the ls1, but id like a 6l so i can cam that 1 day
