How much power have you seen with a 1-3/4" primary tube on a 400 cu in sbc?

When the Pro-Stock trucks were running (10-15 yrs ago) I saw some of them with 1-3/4" stepped to 1-7/8". Not sure if they were 3-step or just 2, but they started out at 1-3/4". Those engines made 900+hp and were 358ci if I remember correctly.

I have found on bracket style 23 def 400-430 inch engines...670hp seems to be the brick wall

When I put a 1 7/8 into 3.5 collector they jump up 15 to 20hp
