afco 3850 for the rear 3855m for the front .
afco recommended me there 125# springs
with a guesstimate of 1600 pounds on the rear
my car is 3375 with me ready to race
what size springs do other duster guys use, Did you do your home work and measure the length required for your car???? I would not just go with there recommended shock length, Take the time and measure.

We run Strange DA on the rear of the heads up car. They do have their Pro Mod valving in them too. Been great for us and we are handcuffed by running a very short shock because of the body style of the car.
As for spring rate you just need enough spring to hold the car up with the shock at ride height.

Hood scoop or no? Fuel pressure on big end? RPM where it is occuring? More info on the combo and whats going on up top will help.
