I actually almost did that SC 3800 swap. I even went so far as to secure an engine that was a target of opportunity. Problem I ran into was when I tried to buy a Fiero. The only ones I liked were the GT models in the last couple years or production. And people are pretty proud of those price wise.
From what I read it was a pretty easy swap.

HPP had a geeat article on one.
I personally prefer the Quad4HO swap - but I am admittedly bias.
Putting a Quad4 in a Fiero in either LO or HO trim would be lighter than either original engine, and have more hp to boot!
I had actually read that the Quad4 was slated to replace the Iron duke for 1990 Fieros... that would have been a game changer (at least until the automotive press whould have given the Quad4 a bad rap for the OE head gasket issues)...
