318 1/8 time improvement

I heard about draggy app honestly I live on a boulevard. Its like drag race city on fridays lol

Do you think a 650 or a 750 double pumper would be a better choice. I think just the switch over from a vacuum secondaries Holley 600cfm to a double pumper would help my 60ft.
I don't know what a 750dp would do for 60 ft, but I'd bet it would sure help mph!.(over a 600vs)

I've got the draggy ap on my phone, but I haven't used it yet. How fast IS a 12500lb box truck? Lol.
