I thought for sure quite a while back that the 3.5 was being developed as a replacement for the 3800 line... Guess I was wrong, and yes its very possible that cost plays a large factor...
I just love pushrod engines, always have and still do....
But on the same note DOHC can be very fun....lol
One day I may have one

It'* a DOHC motor so it'll be much bigger up top.
and yes, isn't the cam on a 3800 pretty flat ?

I think some are thinking of the 3.6L that Cadillac uses. The 3.5L was only used in the Intrigue and Aurora. It was only used from 99 until 2002. It only had a three year run and it was designed by Oldsmobile. :( When the Intrigue was discontinued in 2002, the Aurora also dropped the 3.5L as an optional engine. all 2003 Auroras were the 4.0.

WIth that graph it makes me wonder even more why pontiac/buick didn't use the 3.5. It'* just a lot more powerful in the higher RPM'*. It doesn't have the lower end torque at very low RPM'* as the 3800, but it does have the higher gear ratio to make up for it, and it'* rated at the same fuel economy as the NA 3800. If only I could ask GM myself. lol. THat gear ratio must really make a difference though because the acceleration from a dead stop is very similar between my Aurora and my brother'* 00 SLE. Once you get above 3,500 RPM the 3.5 starts pulling away hard from the Bonneville though.
