I was doing some checking on the net and am finding that the 350 will bolt great to the existing 305 setup within the car now

My dad has a 383 built up from a 350 block and is offering it to me for 450 which is a hell of a price

however

what chip will i need to use?
engine mounts?
will the ac brackets fit up?
will the tbi fit and work?
should i stay with the performer edlebrock that he alredy has on it?
go with a tripple core radiator?
wireing harnesses on the new motor?
HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11
