  1. Frame limitations for a '37-'38 Chevy truck frame.

    General Rodding Tech
    Hey guys, just planning out the next steps on my build. I have a '38 Chevy half ton, which has the same frame as the '37's. Im just a bit worried as to how much HP/TQ I can put under the hood, but Im quite leery, as the frame is only 1/8" thick steel, thats formed into a 4" steel C channel...
