I would rather replace the engine with a low milage 5.3 from the junkyard, but I dont know if the wiring or ECU will work? Does anyone know of a swap thread or website about swaping the vortec 5.7 to the vortec 5.3?

What about the tranmission? I might as well replace that with a new one. Will I have any problems going to the 5.3 tranny 4x4?

Thanks
Nick
