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)...

The Quad 4 is good if you can keep the head gaskets from blowing and the timing chain on the sprockets. JMO.
The problematic water pump was normally the culprit for both.

Just think of the tech improvements you will see in your lifetime. I am close to 50 and cars have come a long way from the leaded gas car technology of the 60's and 70's. You will be driving your flying car one day bitching at some young kid that you remember when cars ran on gas and not tap water.

The head gasket issue is fixed with a modern felpro style gasket - not an OE (victor reinz) gasket...
i haven't had any issues with a water pump...
timing chain problems are typically because the chain was worn out, not set properly, or the tensioner crapped out...

Someone showed up with a modded quad in a 4 cylinder fwd stock car and ran lap times comparable to a 2300# 400HP V8 powered tube chassis car, I was impressed as were most that had a watch on it. That thing sounded like a chainsaw! This is the grass roots of circle track racing youth ingenuity.
