Spring an shock setup on my 1971 C10 SWB.

[Blue Rat]

Would like to have a little help with setting up the suspension setup on my C10. The engine is going to be about 550 HP BBC an a 150 shot. The rear end is a GM 12 bolt. The tranny will be an auto with a converter about 3500-4000 stall. Some street driving around town never any long trips. Track a few times a year.

Thanks for any help. Will be gone the next couple days to the swap meet at Petit Jean mountain.
