For pulling heavy cars to quick ET I like more cubes.
Or put the car on a diet.
400 cubes should get it done and I do not feel 210cc head as a large head for those cubes.
And comparing an LS head runner volume or BBC runner volume to the gen 1 SBC head is not fair as I know the runner from intake face to the long side of the bowl in longer and this adds to the volume. subtract that extra length and see where you stand.
But shape is much more important than just raw CC numbers.
Lighter car 3300 lbs 357" flat top SBC with bowl ported 1978 305 2 barrel heads with stock 1.72-1.50 valves.

Small head small cam lighter car.
The 400" should get it done.. get it dialed in.
I have some very big heads I want to try one day 2.3" tall intake runner but it will get a [email protected]

And I will drive it long distances if my wallet holds out.
