plus the nickle content. block, heads, crank, all high nickle.Considering the Buick 350 is a strong, skirted block I am also surprised it weighs so little. It must be its compact size. Of course the Olds 350 weighs the same or less than the sbc 350 and Olds is much bigger in every way.
Biggest question is, how will you be using it?
My vote for an occasional cruiser; I'd probably replace wear items with Moog and forget about it. Probably go tall balljoints too since you'redoing them anyway. If you haven't already, a fatty front swaybar.
Poly bushings are stiff and sometimes squeaky. Stiff springs are harsh around town. Stock brakes are okay -- not great.
Your tires are kind of the limiting factor now anyway. I love the look of those rallys and whitewalls, BTW.
I'd save expensive performance parts and dash rattles for a track day toy.
