1980 Ls1 Upgrade help needed !!!!

[baddaw]

Hey everyone,

I have a 1980 stepside c10 gmc swapped with ls1 (450HP)

and now im looking into upgrading the suspension and few other things

so here whats im looking for :

Defrential (12 bolt if u think its better)
Axels
Drive shift
Control Arms
Ball Joints
Springs
Shock Absorbers
Complete Boushing Kit

im looking for more control and stability so need high performance parts for a daily use and need to know what parts should i change and what stock parts can be fine.

And im also wondering to change it to manual transmision what do you think ? if you also think it would be better then which transmision do u preffer i should get for ls1 with 450hp ? ( not a 3spd )

i know that i have a big Question mark behind me im just new to c10 and allways wanted to build one, so here i am planning on what to do

by the way ill start my full project build in the project section as soon as i plan the whole build up first

badly need your help with this

thank you for your time =)...
