swapping from a 2.8L to a 4.3L

I was planning on buyin a 4.3L engine, and i was wondering if it probly would bolt right up to the stock engine brackets. Also i have a 5 speed manual with my 2.8L, could i use this or would i have to buy another trans. And also I was planning on turboing the 4.3L. How much power might i get out of it? and anyone kno what any probs might occur

welcome to AF if ive missed you to this point, sorry... no, your transmission wont work, and it will be almost as costly as a 350 swap as far as i know...and the problems with turboing, are if the pistons are not forged, there will be piston parts in the oil pan if you boost more then 4 or 5 lbs.
