I've actually heard of this my neighbor has a grand prix gtp that the bottom end blew up in and the mechanic he took it too replaced it with a 3500 block I almost didn't believe him until I called the mechanic to clarify oddball swap imo
With cross-bolted mains, the main weak point is pistons, then rods. But Mars' boneyard 3400 ran 11's, I believe he still has the same 3400 in his Fiero to this day, N/A though. I think it put down somewhere around 225whp too.

They do, but last time I checked their intake manifold didn't fit the 3x00 heads. Also, the supercharger displacement is on the small side. While it's adequate for a 2.8 V6, it would struggle to keep up with a 3400.

They are what they are. They were not built for forced induction. The 3400 crank and rods are the same as the 3.4TDC units and are good to over 7000RPM, put LT1 lifter springs in the lifters, put in a cam that let's it breath and good valve springs to eliminate float and it will make power all the way out there too.
No, they are not as stout as 3800s, stock for stock. I am a huge fan of the platform, but be realistic. Although, really, I wouldn't turn down 381/353 at the wheels...
Supercharger at 13psi though... I'd rather have a turbo.
