1970 C10 (Suspension/traction questions)

[Swiftshifter68]

Definitely keeping an eye on this thread, as my '67 has a similar turbo'd iron-block LSx combo', albeit with a T56 Magnum and milder 3.42's. I've got a bit more weight behind the axle with my underbed fuel tank, same Viking d/a coilovers with 350lb. springs, with CPP/Speedway 2" drop front coil springs (1,100lb-in) and cheapie GR-2 front shocks on relocators.
Hoping to have this sucker running/driving in the next few months, as the Redwood Rally 2024 is quickly approaching on the horizon! (September 17-21) A Truck Class has been added this year, but I'm stickin'(!) with the 3-Pedal Class!
