Many years ago, I had MOOG #6452 springs installed, Monroe Magnums, went with Urethane bushings in the front end rebuild, Eaton Detroit TruTrac with 3:73's in the rear axle installed by Robert Thomas in Hesperia CA, a set of Firestone Destination AT 225/70/15 to roll on.
With the new springs, it sat up an inch or so, felt super nimble and accurate, handled Very well, and rode super smooth with the set up.
I had wanted to try the 235/75/15 next time around with the new gearing, 30" tire or less for handling/mpg/parts longevity.
People would say get big/bigger tires, I say if you pay for the gas and repairs, (I am as cool as I am gonna' get) lol.
MPG's went from 14+ to 18+, found out during break-in of the new rear gears, old were 2:72.
The 700r4 was rebuilt heavy duty, too bad the college screwed up on the 5.0 lol.
Had to sell the truck due to disability requirements...oh well.
So, if you want it to roll easy, that was my design back then on the 84' C10 step side.
If you want it to look cool and don't care about handling and mpg's, dream big, spend the dollar and go build exactly what you want, we only get one trip on the ticket, no U-Haul behind the hearse, no refunds or returns.
