3.5 V6

Yea I was wondering if anyone could help me out I am looking to drop a new engine into my 96 sunfire se (2.2). I have been reading about these guys dropping 3.8 into their cavaliers and sunfires and stuff but then they tell you I did none of the work my sponsors did. Well I am not look for someone to do all the mods need for that and I know I wont be able to do those type of mods so I gonna go with something that might actually fit a bit nicer. I was wondering if a 3.5 would fit without do all the mods to the cradle and if anyone could give me a sorta step by step. I am not completely retarded with moding a car and if I do need help I ll just asked my fiancee's dad but you guys out there know where I am coming from I dont wanna go asking if he will do all this to help me out and yea just anyone out there got anything to say to help.
