1980 Ls1 Upgrade help needed !!!!
 

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 =)...

A 12 bolt is minimally stronger than a 8.5 inch 10 bolt. I ran a 8.5 in a 10 second malibu for a long time with zero problems. A good carrier, a set of axles, and c-clip eliminators will go a long way towards making the 10 bolt live. You would need to make the same changes to a 12 bolt if you plan on beating on the truck.

4.5/5.5 static drop with spindles/springs up front and a flip in the rear. Add a rear sway bar, and rebuild the wear parts while you are at it. Should provide for a fun street ride.

As for the manual transmission, the only one I would consider would be a T56. Would be a easy swap since they came behind the LS1. It will handle the power you are making.

Just my $.02.
