Ok, my 85 car still has a 2.8 in it, a 3.4 will bolt right in and use the original stuff (smog guys would never know) I was thinking that the more modern aluminum heads and intake would look stock if someone milled off the 3.4, or somehow made it say fiero, maybe sacrifice the upper part that says "Fiero" and patch/weld that into the newer intake?
Making more than 200 up with a little V6 that bolts right in sounds pretty cool to me, if it can be made to look stock to fool the smog guys. This post was about the breathing on a V6, what better way than a top end swap?
Keep in mind these cars were built before most of the young smog tech guys/girls were born.
If this is all obsolete info, what is the new s**t? Remeber, boost or supercharger, or something obvious= NO SMOG FOR ME.
Trying to make WAY more power, without setting off the alarms, how do I do that? I am considering a" plug in" entire cradle to run a V8 and switch back to stock at smog time.

If you really want 'way more' power, you are looking at engine swaps or turbos. The cast iron heads have inbuilt limitations. A halfway point is going to the better breathing alloy heads but it isn't going to look the same.
How it performs is a matter of power to weight. I have 200 bhp hauling about 2100 lbs. in my rebodied MG and it runs about dead equal with an MGB with a tuned Rover V8 in it. Plenty for fun touring use. Yes, I did really think about sticking my turbo 3.2 (which was closing on 300 bhp) in it but that would have been overkill and the inherently inferior weight balance of a front engined car would limit adhesion on starts anyway.
The Original V6 is a flawed engine that many of us are fond of, but not that suitable for high output levels. Lots of modern engines are much better. If you want to stay GM powered, look at the Ecotecs. Here is a Cobalt SS with 600 bhp out of a 2.0.
I run a 2.0 ecotec with 375 bhp that returns 30 mpg in my street car.
