New front shocks but truck still bouncy

[Backpayne]

My '64 has new KYB front shocks yet it still bounces going down the road. It has that boat/floating feeling and it bottoms out easily. The new shocks did not change anything.

Could the springs be weak? They look like they have been cut. I have stock front springs that have more coils, so I am wondering if the front springs currently on the truck are from another vehicle with a lower spring rate.

Any suggestions or ideas?
