im running a 3300 lb duster



I went from the smaller 1.6 exhaust to the (newer stock) 1.74 size. Intake valves are stock size.
I did a little backyard smoothing of the ports, I didn't re-shape anything or remove any material, I might have made it slower.
Shortblock is a 40k original mile 1966 440, never touched, bone stock.
Heavy all steel street Challenger(less fiberglass T/A hood).
Hemi 4 speed with 4.10 rear gear.

I would think 11's would be real easy in a lighter A body as long as you get it tuned and dialed in right.
