Hey guys first time poster, as you can probably tell. I have a friend who is looking to build a 396 to around 500+ HP. He is looking into possibly buying a 79 or so G body Cutlass for the build. I was wondering, as I know nothing of the car and am too lazy to do any research as its not going to be my car, but I was wondering if they are a full frame car and if it's a solid frame to put that much power to it without worrying about it twisting? Thanks for any help!
