Hey, I'm getting ready to swap a 3.4L engine into my fiero, but haven't bought all the parts yet. I have read A LOT of swap threads and now have just a couple questions if someone could help me out...

The car: 86 Fiero (not GT) 2.5L Auto

I didnt want to have to deal with the wiring, so I heard of some ppl carbing theyre 3.4L. What do they do for their intake manifold? Also, what kind of carb (cfm) are they using? This will be the first engine I swap that isnt the same engine that came out, so I'm thinking the easier the better.
Can anyone post a build link where someone carbed their 3.4?
Can I leave the 3.4's accessories on there instead of putting on the ones from a 2.8? what kind of problems would I run into w/ the alternator, etc? It would save me having to go buy a 2.8L since the engine in the car right now is a 2.5.
Thanks for the help!

Also, what all year ranges of the 3.4 can I run. I know that the 93-95 camaro/firebird are best...but what all will line up with the tranny and mounts? thanks again!

The intake manifold is made by Edelbrock and can be bought thru Jegs or Summit.
The carb is a 4-bbl 390 cfm Holley.

You can find many threads on the 223hp 3.4L I built. Just use the search and look thru the archives under my screen name and 3.4L carb.

As an example:
