So I sold my 77 GMC it was not gonna be a fun project unless it was pre-smog. I came up on a nice 75 c-10 and well on my way to completing my LS swap. I shaved the front bumper and sectioned 2” from each side to get a closer fit in the front. It’s currently got a 90’s 350 I believe a 3 speed trans with a heads vendor. I have an iron block 5.3 with 50 k on it that I just tore apart and a 4L80 trans to back it up plan on going boost.
