Need some help dipping into the 11's

Your Horsepower computed from your vehicle weight of 3400 pounds and MPH of 89 is 191.95. assuming 30% drivetrain loss your getting 260HP at the flywheel

a 416 11:1 should be waaaaaay more

i've never heard great things about demon carbs... get yourself a 750HP holley and dont look back

mech secondaries are gonna get you better slips when racing

i doubt the cam being out of degree could be that much of a loss. what do you have the valve lash set to?
