6 cyl. --> V8 swap, opinions.

I have the oppourtunity to pick up an 86 6 cyl., in primer, for a decent price.

I am looking for opinions, comments etc. about doing a 6-->8 swap.

What things NEED to be changed/replaced? (suspension, brakes etc.)

In the grand scheme, is it just better to buy a V8 stang from the get-go?

Thanks in advance guys.
