Read that... In short, no because it was a Buick and carried the Buick 3800 and the 3400 is a larger version of the Chev 3100, a Chevy 60 degree V6.

If you're talking about F-bodies then I believe they also had the smaller 2.8L V6 60 degree chevies in the third gen (3100 for 90,91,92), 3400 for half of the fourth and then they switched over to the buick 3800.
