Let's Build a 416 with Cast Iron Heads and Manifolds

Guys let’s stay on track. I’m not building a 360, not running headers and not running 4.56 gears. The build is a 416 or 435, J heads, four speed with 3.55 gearing. Carry on.
No manifolds, running headers, 4.56 gears and about 3100.
so drop the manifolds on 3.55s and 3500 lbs you would run what? low 12s
cubes make it a nice street car less gear required still run 11s
something to be said for sucking the paint of cars with headers and gears while looking stock and street friendly manners which iam pretty sure what his build is about
