68 340 Exhaust Manifolds vs TTi Shorty headers

are the high 10 low 11s a-body engines meek running 340 logs manifolds stock intake and carbs on 7 inch tires?

My comments was only related to the 300hp crate motor used in the manifold test and that it was more than just mild. That's the only motor my comment was pointed at.
