Go to junk yard buy all from a gmt900 it's similar as a 800 truck

 

All the suggestions are appropriate along with ditching the rear drum brakes.

 

Put some disc brakes and some 15's in the rear ....

 

Aren't drum brakes supposed to have better static holding power than disc brakes?

 

^^^^^Correct

 

My truck has disk brakes on all for corner. Tonight install the 2step and was foot braking 4lb at 3500rpm. This is the way I did it started braking hard then I put in neutral rev the engine hard and the vacuum built by the throttle blade closing make the brakes go down and makes brake better. Then put truck in gear and push the hell out of the brake pedal. Start pushing the throttle down and the boost starts building. Going to start at this and work my way up. Don't know what the tires will hold.

 

atleast im not the only one pushing through the lights. Didn't want to do a hydroboost as i want to de-clutter the engine bay as much as possible.

Best i managed last year was 116mph on 4.5lbs, said the hell with it when i found a jakes 80e w/d3 transbrake last week lol. Wasn't going to try and fight it anymore.

 

Crazy to see my truck brake torque to 12 psi with stock brakes.

 

cam size, converter size, turbo size an design of kit all play a roll

 

I was pretty impressed to see mine at 30psi+ at 4000rpm
