I just bought a 67 Ranchero that sat in a field for 18 years. I am just finishing the suspension with all new everything including springs, poly bushings and disk brakes. Then 5.0 efi with a C4 trans. I plan on towing a teardrop trailer (800#) and a small amount of camping gear.
My question - Would it be advisable to add overload springs or maybe air shocks? I never had a chance to drive it so I have no idea how much load they can handle.
I've probably been closer to death than that trip, but not much... Although it went without a problem I must say.
As for air shocks--no. Get good shocks that control the car.
Overloads? No. Size up how the rear suspension works. Smooth ride? Too smooth? Does it really sink with 400 lbs in there? (Invite several skinny or a couple fat friends over to stand in the back) What I did with that Mustang was to add a leaf. The old springs were flat at rest, and the new leaf gave me about 1.5-2 inches in the back, and put some arch in the springs. It rode much better after that, since it wasn't hitting the bump stops all the time.
What axle to do you have? Probably an 8" with a 3.25 ratio. You should consider an AOD as you'll be running a lot of revs on the freeway if you're geared that way.
