Hi guys. This summer I was planning on buying a 77 c20 with a 454 and either going to swap it into a 4x4 or a sweet old 67, 68, or 69 c10 or c20. I'm not quiet sure what it was. I was just wondering how hard the swap would be and it it will work. And the motor would come unbolted from an auto and hooked to a manual for an attempt at a rad rod/drift truck. Thanks for your input!
