My '77 k20 rides like a dump truck. Absolutly terrible ride quality. I believe it has a stock front leaf pack with 3 springs. There is currently less than 2 inches from the axle top plate to bump stop, similar distance to the one on the spring.

Have my springs sagged that much? They are basically flat or an upward arch "^"

I swapped in a 5.3 vortec, should weight less than the 400 sbc it replaced?
