Default 4.3 to 5.3 or ls swap??

I have an 89 s10 blazer with a 4.3 in it.
I thinkin about swapping in a Ls1 and a T56. Or A 5.3, LH8 from a Colorado.
if I go the LH8 route, How much am I lookin to invest in a motor/trans (roughly)??
Any particular year or donor that is the best candidate??
What issues will I run into??
And any suggestions as far as ECU's and harnesses are concerned??
And finally, any miscellaneous info I missed, or didn't consider.
Any and all info is appreciated.
