Hi all! Just bought a 1977 k20 has no engine I decoded the vin and it says that a 400 small block was the original engine. My question is will the harness fit the 454? Also should I be concerned affecting the other drivetrain components such as transfer case, rear diff? I already ordered my engine just want to know what I’m looking at. Will it mount up right? Thanks guys
