Hello everyone,

I am new to this forum and have yet to set up a profile because I have a more pressing question. I own an 86 K10 custom deluxe that I need to swap the SB350 out of the engine block cast number should be 10051184 or 10066036 I can't be sure until its out unless maybe I were to cross-check that with the VIN somehow. I also have an 350 from the previous generation cast number 3970010 and I'm tryin to find out if that can be cleanly swapped into place and also bolt-up to my 700r4. Any help or information helps. Thank you
