Better check your state laws. That is illegal in alot of states.

Its goona be a pain if you want to make it fuel injected.

y is it illegal???

Going from fuel injected to carb'd. Fuel injected cars burn a lot cleaner. It's an emissions thing.

Your not allowed to put an older engine into a newer car. Its because of emissions laws.

Well aside from it being illegal... What can actually be expected?

oxfordgt

You have to change to a 94-95 k member. Not sure what tranny is in the 99 v6 but if its a t5 you good. You will have to get an ignition system for it depending on what you want you to run I would suggest using a vacum advanced distributer. Fuel system is easy if it is a returnstyle you just have to T the line and and run it to the carb and return line. Put an inline fuel pressure gauge in it just before the carb so you can make sure pressure stays below 10psi. If it doesnt have a return style fuel system (dont know much about v6s) then you will have to change to either a carb friendly electric pump or a mech pump. Which ever you choose make sure you decide before you put the engine togather so you wont have to change timing covers later. Exhaust will have to be fabbed in there but shouldn't be much of a problem. Thats all I can think of for now.

hope hes got the money for this either way. do a search for everything your gonna need (new suspension, radiator, rear end, tranny or at minimum bell housing, etc...) the v8 into a v6 question comes up about every other day in the v6 section.
