So you'll see me loitering here too now and asking lots of Q's

I want to put my carby 350 chev and auto in the Bundy so I'm just wondering what springs would be best considering the extra weight over standard.
The chev is all iron too so pretty weighty.
Obviously I want better flex and a bit of extra lift but not too much body roll.
Would adjustable shocks help there?
Thanks, sudso
