Outer Limits 4x4 Board

Hi guys, I'm normally loitering in Isuzu tech but I've just taken delivery of a SWB RJ70 1985 coil sprung Bundy which I am going to build up for a toy as my Rodeo is a bit limited suspension wise.
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

80 series front coils will give you 4 inch lift and enough spring for the v8
pm me if you want some
