"Best" is a very subjective word. Best horsepower is the series III 3800SC used on the 2004-2006 Grand Prix but as drive by wire engines they are a bit more difficult to swap as you'll need to adapt the earlier TB and MAF to get it to run correctly. The auto trans mounts are also different than on the 95-2002 transmissions. The best for being easier are the 95-2002 3800SC engines. Both are good engines but are also quite old at this point and hard to find with low mileage. If I were to do a swap today it would be for the lighter GM LFX V6. Its a more modern design that provides 300HP stock. This engine has been used in engine swaps many times but not much in Fieros so far.
