Re: Project: Big Grapefruit
Can't agree more. The 157" frame is the king of the LD truck frames (8.18" section height, 2.97" flange width, 0.224" thick, 7.29 section modulus).
Numbers work out to about 99% stiffer than a K20 frame, but then even a C20 (127") frame is about 8% stiffer than a K20. Don't remember the kickup being that minimal but go with what you see. If you are doing a 4x4 conversion I have some thoughts I'd like to run by you.
