Dana 60 S60 or Ford 9"

now here is another topic I reckon but I will go ahead and ask it here. I have been planning to build an SS/AH chassis spec build for this car, but I also considered building the car like the old pro stock style where they still ran leaf springs. I wouldn't turn as much ET with that set up but I am not trying to tear the world down neither. If I built the chassis this way, it would be a lot less money and still fun which is what matters. and also I wouldn't ever run the AH class just because it is way out of my budget to even try it. what do y'all think?
You might consider a long ladderbar suspension. Simple, easy to set up. Not sure but someone should make a 34 to 36 inch setup. The front mount may need to have a fairly low bottom adjustment hole due to the torque you will have. Consider a 4.10 to 4.30 ratio rear gear. A 604 isn't going to need much gear. Big Gun afco shocks custom valved to your chosen combo would be my choice. Do some math on how much torque is g o ing through the axles at the hit. That will help you see the need for properly valved shocks. Engine torque x 2 ( converter) x SLR = axle torque.
