I traded for my SHOTROD truck, first thing I did after I got it running well is rebuilt the stock brakes completely( cost little over $150 doing it all myself!), I would like to upgrade to discs myself.
after building and driving many pre 70's"hotRod" Chevy Trucks I have learned that drum brakes work but IF it goes Fast it needs to stop Fast!
My Main Point is that dont build a 600HP motor and then run the stock drums.
Good luck,
