I am looking into doing this sometime around May. I'm not a mechanic, but I have a good mechanical aptitude. I'm sure I can tackle this, except for the welding stuff but I'll find someone to do that part.
From what I've read so far, getrags routinely handle HP in the range of modded 3800s. Fiero guys put SBC V8s on them for Petes sake! Its the case thats the weak link so long as you have a good clutch. Compared to swapping in an F40, the 282/284 seems like a bolt-on job. Just ask Fiero guys, or even kuntzie. They can handle it just fine, but like any car part, if you beat the ever-living-crap out of it its gonna break.
The auto trans is the only, I mean only, thing that I didn't like when I bought my car. I had a '90 sunbird 5-speed(282) that I loved to drive even tho it was like 100Hp at most.
EDIT: So I got an answer on this 282/284 thing. The 282 has been known to break at 330WHP. The 284 seems to handle much more, Kuntzie has been able to throw nearly 600HP at his 284.
