Otherwise I would look at a 3800 or a 3900 vvt engine
Ditto to both. Rcheee's products are not well engineered and have several serious design flaws.
The 3800 V6 is almost bolt in with aftermarket brackets and the supercharged engines can top 300 RWHP easily. The 3500 & 3900 60 degree V6's are also very easy swaps. They top out a bit less than 300 RWHP naturally aspirated, though.

all that being said, I think a N* in a fiero is probably the best looking V8 in a fiero, and they sound/perform awesome.
With some relatively minor work on his LS4, FieroGuru made 380 RWHP, which is a number yet to be seen by a N/A Northstar in a FIero. So yeah, the LS4 definitely has the buildability advantage.
I'm aiming for 450 RWHP. I have the heads and intake to get me there figured out, but getting the cams to ice the cake will be fun.

Lol... that's a whole new level of futzing. I @$$ume that the LS4 drive wouldn't work because the dry sump timing cover bulges at the bottom to make room for the bigger oil pump.

Yep thats exatcly the problem.
The vette FEAD is supposed to be the shortest of all the LS family outside of the LS4 though. So, we will see how it all lays out. The LS3 version if the dry sump has it's own unique problems of compatibily issues in the LS family. Mixed with the even more unubiquitous LS4 idiosyncrasies it will end up to be an oddball. Once i get the time to start bolting those parts together, ill see how much of a bad decision I made.
car.
