I'm sure this has been asked and answered but if I want to do the 3800sc swap will this motor fit the stock tranny (85 GT 4 speed transmission in an 85 SE)? if not where can I find adapter kits? thanks

Yes, IIRC all transmissions that came in the Fiero have the same bolt pattern as the 3800. The muncie (which is your transmission) also happens to have the strongest casing that was put in the fiero. Of course, you won't be able to abuse the trans too much because the power will break it. For in town driving, the 4 speed is probably the best way to go because of the gearing. If you drive on the high way a lot, you might want to consider upgrading to a 5 speed F23 trans.

BTW, welcome to the forums!

Yes. All 3800s use the FWD bellhousing

I'm sure its no worse on the highway than my current stock automatic set up.. that thing costs a fortune on gas. Do you have a recommended build thread to follow by chance?

This is a great start, it isn't on the forums tho:

http://www.gmtuners.com/swap/3800.htm

Here are required parts:

http://www.westcoastfiero.c.../conversion_info.php
(scroll down and choose manual ac or without ac.)

This one is good:
http://www.westcoastfieros....um_posts.asp?TID=608

and one more:
http://www.fiero.nl/forum/Forum2/HTML/121858.html

Make sure you read into this information. It seems like a lot, but the more you know the better off you are. And of course, always have patients and pay attention to detail.
BTW, start a build thread here so that people can watch your progress, and help you out along the way. One of the first things you should do is download PIP:
